  • An Investigation of the Crystal Growth of Heavy Sulfides in Supercritical
    AN ABSTRACT OF THE THESIS OF LEROY CRAWFORD LEWIS for the Ph. D. (Name) (Degree) in CHEMISTRY presented on (Major) (Date) Title: AN INVESTIGATION OF THE CRYSTAL GROWTH OF HEAVY SULFIDES IN SUPERCRITICAL HYDROGEN SULFIDE Abstract approved Redacted for privacy Dr. WilliarriIJ. Fredericks Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin, lead, mercury, iron, zinc, antimony, arsenic, silver, and cadmium was determined and found to agree with the theoretical result. Hydrogen sulfide is a strong enough oxidizing agent to oxidize stannous sulfide to stannic sulfide in neutral or basic solution (with triethylamine added). In basic solution antimony trisulfide is oxi- dized to antimony pentasulfide. In basic solution cadmium sulfide apparently forms a bisulfide complex in which three moles of bisul- fide ion are bonded to one mole of cadmium sulfide. Measurements were made extending the range over which the volumetric properties of hydrogen sulfide have been investigated to 220 °C and 2000 atm. A virial expression in density was used to represent the data. Good agreement, over the entire range investi- gated, between the virial expressions, earlier work, and the theorem of corresponding states was found. Electrical measurements were made on supercritical hydro- gen sulfide over the density range of 10 -24 moles per liter and at temperatures from the critical temperature to 220 °C. Dielectric constant measurements were represented by a dielectric virial ex- pression.

The views and conclusions contained in this document are those of the author(s) and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government. Introduction In recent years, a great deal of progress has been made in the development of geoenvironmental models to predict the potential for environmental contamination associated with mineral resource development (c.f. du Bray, 1995; Plumlee and Logsdon, 1999). The application of such models to current, prospective, and legacy mining sites provides industry, public land managers, and environmental quality agencies an important tool for developing management and remediation strategies. An essential aspect of developing such models is access to high quality water, sediment, and soil chemistry data sets from well-characterized mineral deposits. These data sets can be used to predict the identity and levels of potentially toxic trace elements based on similarities in ore deposit mineralogy, host rock lithology, and other geo-environmental variables.

Clinocervantite, appearing generally as aggregates of single prisms elongated along [001] or twinned on {100}, is co]ourless, transparent, with vitreous lustre, biaxial, with the lowest measured ] ] refractive index a,' = .72 and the highest one y' = 2. O. The strongest lines in the powder pattern are dill = 3.244 A and d311 = 2.877 A. The crystal structure, space group C2Ie with a = 12.061(1) A, b = 4.836(1) A, ] e = 5.383( I) A, ~= 04.60( 4)" and Z = 4, has been refined to R = 0.020, confirming the new mineral to be the natural analogue of the synthetic ~-Sb204 already known. The structures of clinocervantite and cervantite may be regarded as built up by stacking layers of nearly identical structure and composition accounting for both polytypism in the Sb204 compound and twinning of the clinocervantite crystals. Key-words: clinocervantite, crystal-structure refinement, cervantite, twinning. Introduction Occurrence, physical properties and chemical composition During the study of rosiaite (Basso et al., 1996), an associated new mineral was found in materia] Clinocervantite occurs in litt]e cavities of a rock from the Cetine mine, central Tuscany, Italy.

  • Toxicological Profile for Antimony
    ANTIMONY AND COMPOUNDS 11 CHAPTER 2. HEALTH EFFECTS 2.1 INTRODUCTION The primary purpose of this chapter is to provide public health officials, physicians, toxicologists, and other interested individuals and groups with an overall perspective on the toxicology of antimony. It contains descriptions and evaluations of toxicological studies and epidemiological investigations and provides conclusions, where possible, on the relevance of toxicity and toxicokinetic data to public health. When available, mechanisms of action are discussed along with the health effects data; toxicokinetic mechanistic data are discussed in Section 3.1. A glossary and list of acronyms, abbreviations, and symbols can be found at the end of this profile. To help public health professionals and others address the needs of persons living or working near hazardous waste sites, the information in this section is organized by health effect. These data are discussed in terms of route of exposure (inhalation, oral, and dermal) and three exposure periods: acute (≤14 days), intermediate (15–364 days), and chronic (≥365 days). As discussed in Appendix B, a literature search was conducted to identify relevant studies examining health effect endpoints. Figure 2-1 provides an overview of the database of studies in humans or experimental animals included in this chapter of the profile. These studies evaluate the potential health effects associated with inhalation, oral, or dermal exposure to antimony, but may not be inclusive of the entire body of literature. A systematic review of the scientific evidence of the health effects associated with exposure to antimony was also conducted; the results of this review are presented in Appendix C.

Samples collected on ore and waste dumps were used to identify and characterize the previously uninvestigated suite of supergene mineral phases by standard mineralogical techniques. The following species were determined (in alphabetical order): annaber- gite, arseniosiderite(?), gypsum, hexahydrite, hörnesite, pararealgar, roméite-group minerals, rozenite, scorodite, sen- armontite, stibiconite, sulphur, tripuhyite and valentinite. Their occurrences are described and their local conditions of formation are discussed. High-resolution Raman spectra of hörnesite, hexahydrite and rozenite are provided and com- pared with literature data.

Crystals, druses, and crusts of schafarzikite occur on fractures in quartz- carbonate-stibnite hydrothermal ores. The Sb mineralization is bound to black shales and phyllites in a zone of actinolitic rocks. Associated minerals include ankerite, berthierite, stibnite, valentinite, kermesite, senarmontite, and gypsum. Prismatic crystals of schafarzikite are 0.1–1.0 mm, rarely up to 1.5 mm large, with the dominant forms {110}, {121}, {112}, {010}, {221}, {131}, and {231}. The optical properties are: uniaxial, with relatively strong pleochroism in red-brown tints; refraction indices higher than 1.74; the average refraction index, calculated from the Gladstone-Dale equation, is 2.001. The physical properties of schafarzikite from Pernek are: dark brown to black color, adamantine to metallic luster, brown streak; translucent (brown to orange) in very thin fragments; good {100} cleavage and perfect cleavage along unindexed planes parallel to z axis, tenacity-brittle; VHN10g micro- hardness = 251 and 278 kp/mm2 (for two cuts with differing orientation), corresponding to Mohs’ hardness of 3.5–4; calculated 3 density Dx = 5.507 g/cm .

  • Antimony Trioxide [CAS No. 1309-64-4]
    Antimony Trioxide [CAS No. 1309-64-4] Brief Review of Toxicological Literature Prepared for National Toxicology Program (NTP) National Institute of Environmental Health Sciences (NIEHS) National Institutes of Health U.S. Department of Health and Human Services Contract No. N01-ES-35515 Project Officer: Scott A. Masten, Ph.D. NTP/NIEHS Research Triangle Park, North Carolina Prepared by Integrated Laboratory Systems, Inc. Research Triangle Park, North Carolina July 2005 Chemical Name: Antimony Trioxide CAS RN: 1309-64-4 Formula: Sb2O3 Basis for Nomination: Antimony trioxide was nominated by the National Institute of Environmental Health Sciences for chronic toxicity, cardiotoxicity and carcinogenicity studies due to the potential for substantial human exposure in occupational settings and lack of adequate two-year exposure carcinogenicity studies. Additional studies of antimony trioxide are of interest, in lieu of studies with antimony trisulfide or another antimony compound, considering the higher volume of use and magnitude of human exposure, and the lack of two- year exposure carcinogenicity studies for any antimony compound by any route of administration. Antimony trisulfide was nominated to the NTP by the National Cancer Institute in 2002 for carcinogenicity studies (http://ntp.niehs.nih.gov/ntpweb/index.cfm?objectid=25BEBA08-BDB7-CEBA- FC56EAD78615ADCF). Subsequent to the nomination review process, the NTP concluded that antimony trisulfide should not be studied further at this time for the following reasons: 1) antimony trisulfide does not appear to represent a major form of antimony to which humans are exposed; 2) carcinogenicity studies of antimony trisulfide is unlikely to lead to a sufficient understanding of the carcinogenicity hazard for antimony compounds as a group; and 3) there is concern regarding the safe handling of pure antimony trisulfide in experimental settings due to its flammable/combustible nature.

Natural valentinite from Su Suergiu, Sardinia, and also artificial valentinite made by subliming chemically pure Sb20a above its inversion point, havc been studied by thc W ei13en berg method. The structure has been completely and uniquely determined. The three symmetry planes indicated by W ei13en bcrg symmetry study confirm the orthorhom bic charaeter of this crystal. These all prove to be glide planes, which per- mits a unique determination of the space group. An intensive intensity study has been made resulting in a unique determination of the correct antimony equipoint com- bination and all antimony parameters, and a unique determination of the oxygen equipoint combination and oxygen x and y parameters. The only parameters remaining undetermined by direct intensity deduction are the two which fix the elevations of the two kinds of oxygen atoms.

  • Antimony Trisulfide 1345-04-6
    SUMMARY OF DATA FOR CHEMICAL SELECTION Antimony Trisulfide 1345-04-6 BASIS OF NOMINATION TO THE NTP Antimony trisulfide is brought to the attention of the Chemical Selection Working Group as a widely used chemical with insufficient information available to assess its carcinogenic potential. This chemical came to the attention of the National Cancer Institute (NCI) from a review of chemicals viewed as “not classifiable” as to carcinogenicity to humans (Group 3) by the International Agency for Research on Cancer (IARC). IARC noted the limited evidence of carcinogenicity for antimony trisulfide, primarily from an inhalation study in which rats were exposed to antimony ore concentrate for one year and then held for up to 20 weeks post- exposure. In this study, interstitial fibrosis and alveolar-cell hyperplasia and metaplasia were observed in both males and females and lung tumors were observed in the females. This limited study has been challenged in various reviews because of impurities in the test material, including small amounts of arsenic. Exposure to antimony trisulfide in its various forms, including grey antimony, antimony orange, and orange concentrate appears to be moderately high. The National Institute for Occupational Safety and Health (NIOSH) estimates that approximately 27 thousand workers in 34 industries are potentially exposed to antimony trisulfide based on information collected in the 1980s. This compound has a variety of uses, including non-asbestos friction material for brake and clutch linings, fireworks and other
