Herein we synthesized β-TCP by solid state reaction in the presence of increasing amounts of two biologically active ions, namely strontium and zinc, in order to clarify the structural modifications induced by ionic substitution. The results of X-ray diffraction analysis indicate that zinc can substitute for calcium into a β-TCP structure up to about 10 at% inducing a reduction of the cell parameters, whereas the substitution occurs up to about 80 at% in the case of strontium, which provokes a linear increase of the lattice constants, and a slight modification into a more symmetric structure.

Keywords: Phosphate Calcium, Thermal Treatments, Characterization. Abstract. Scientists of different areas research the bioceramics as new materials to substitute parts of the human body. The bioceramics of the calcium phosphate have the advantage present similar chemical composition to the structure of the bony apatite of the human skeleton. In this study, calcium phosphate powder was synthesized chemically using the solution of phosphorus pentoxide (P2O5) and calcium oxide (CaO) necessary for molar Ca/P =1.67. These works aim the study of different thermal treatments, physics and of the microstructure properties. For characterization the bony matrix were used the techniques of: X-ray diffraction (DRX); Scanning Electronic Microscopy (SEM) and Differential Scanning Calorimetry (DSC). 1. INTRODUCION Calcium phosphate based bioceramics have received much attention as bone substitutes due to their chemical similarity to natural bone, their bioactivity and their biocompatibility. This class of biomaterials are promising applications in orthopedics, traumatology and ondontology [1]. These bioceramics may be used for attachment of implants in reconstruction of bone tissue and the controlled release of drugs in treatments ontological.

  • Simple Recycling of Biowaste Eggshells to Various Calcium
    www.nature.com/scientificreports OPEN Simple recycling of biowaste eggshells to various calcium phosphates for specifc industries Nongnuch Laohavisuti1, Banjong Boonchom2,3*, Wimonmat Boonmee4, Kittichai Chaiseeda5* & Somkiat Seesanong6 Egg consumption is very high throughout the world and with it comes enormous amount of waste eggshells. To reduce and utilize these wastes, eggshell wastes were simply transformed to low- or high-purity calcium carbonate grades by washing, crushing, and drying to use as raw materials for producing highly valuable calcium phosphate products. Low-purity calcium carbonate grade was used to prepare triple superphosphate for using in fertilizer industry, whereas high-purity calcium carbonate grade was used to produce dicalcium phosphate dihydrate, monocalcium phosphate monohydrate, and tricalcium phosphate for using in mineral feed and food additive industries. All calcium phosphate samples obtained by simple, rapid, cheap, and environmentally safe method using eggshells and phosphoric acid were identifed and their structural phases and impurities were determined by XRF, XRD and FTIR techniques. Thermal behaviors of raw materials and the prepared calcium phosphates excepted tricalcium phosphate were investigated by TG/DTG techniques. The methodologies described here will be useful to manage eggshells by converting them to highly valuable products, which can solve eggshell wastes problem from industries and communities. This fnding supports the viewpoint of zero waste operation to produce value-added products for obtaining sustainable development, which may be selected as an alternative way for material recycling and waste management in the future. Agro-food from felds of industries and communities produce a substantial amount of pollution every day, so it is becoming urgent to manage this problem1.

  • A Review on Calcium Pyrophosphate and Other Related Phosphate Nano Bio-Materials and Their Applications
    4R4ev. Adv. Mater. Sci. 48 (2017) 44-57 S. R. Vasant and M. J. Joshi A REVIEW ON CALCIUM PYROPHOSPHATE AND OTHER RELATED PHOSPHATE NANO BIO-MATERIALS AND THEIR APPLICATIONS Sonal R. Vasant1 and M. J. Joshi2 1Government Engineering College, Rajkot, Gujarat, India 2Department of Physics, Saurashtra University, Rajkot, Gujarat, India Received: July 29, 2016 Abstract. Over the past few decades, a little word with big potential has been rapidly insinuating into the world’s consciousness, nano. The nano-scale structures permit the control of funda- mental properties of the materials without changing their chemical structure. Living organisms can create amazing ways to produce high performance materials that involve not only creation of implants, replacing bone tissues and organs, but also synthesis of biologically active materials promoting the fullest restoration of tissues and maintenance of necessary functions of an organ- ism. In the biomaterial research field, nowadays, a great attention is given to bone substitute materials, particularly, calcium phosphate based bio-materials play important roles in clinical applications as it possesses high bio-compatibility and excellent ability to undergo varying de- grees of resorbability. These materials show a positive interaction with living tissue that includes differentiation of immature cells towards bone cells and also have chemical bonding to the bone along the interface, thought to be triggered by the adsorption of bone growth-mediating proteins at the bio-materials surface. In the present review paper an attempt is made to cover properties and applications of various phosphate nano bio-materials like calcium phosphate, calcium polyphosphate, calcium pyrophosphate etc over a time span right from 1920 to 2016.
