The supply of these elements in the soil has become limited in some areas as a result of the introduction of high yielding varieties, better and more intensive cropping practices, and increased use of high analysis fertilisers. In some cases, the ob- served deficiencies of these micronutrients have been man- made due to addition of interfering elements for other pur- poses. For instance there is the copper induced iron chlorosis, copper being introduced as agricultural sprays and the phosphorus induced iron and zinc deficiencies, phos- phorus being introduced to meet the phosphorus requirement of farm crops. How to minimise such interactions and the problems of keeping these micronutrient elements available to the plants when applied to the soil have been the sub- ject of intensive researches. -
Calcium Nitrate Calcium Nitrate Is a Highly Soluble Source of Two Plant Nutrients
No. 27 Calcium Nitrate Calcium nitrate is a highly soluble source of two plant nutrients. Its high solubility makes it popular for supplying an immediately available source of nitrate and calcium directly to soil, through irrigation water, or with foliar applications. Production: Phosphate rock is acidified with nitric acid to form a mixture of phosphoric acid and calcium nitrate during the nitrophosphate fertilizer manufacturing process. Ammonia is then added to neutralize excess acidity. Calcium nitrate crystals precipitate via a temperature gradient and are separated as the mixture is cooled. With the ammonia addition and crystallization, a double salt is formed [5 Ca(NO3)2•NH4NO3•10 H2O, referred to as 5:1:10 double salt] and is considered the commercial grade of calcium nitrate. Hence, small amounts of ammonical N may also be present in this grade of calcium nitrate. Calcium nitrate is also manufactured by reacting nitric acid with crushed limestone forming either the 5:1:10 double salt or calcium nitrate tetrahydrate (Ca(NO3)2•4 H2O). The latter product is often produced as a wet crystal or a mesh and is subject to specific regulation with respect to handling and safety. Prilling and granulating are the most common methods of making particles ready for field use. Calcium nitrate is very hygroscopic (absorbs water from the air), so when intended for soil application, proprietary coatings are applied to minimize moisture uptake. Calcium nitrate intended for hydroponics or fertigation does not contain a conditioner, or it may be sold -

The properties of the binary glasses were compared with those of pure silica Stöber particles. The direct addition of calcium chloride (CC), calcium nitrate (CN), calcium methoxide (CM) or calcium ethoxide (CE) at 5 mol % with respect to tetraethyl orthosilicate in the reagent mixture gave rise to textured, micron-sized aggregates rather than monodispersed ~500 nm spheres obtained from the pure silica Stöber synthesis. The broadening of the Si-O-Si band at ~1100 cm−1 in the infrared spectra of the calcium-doped glasses indicated that the silicate network was depolymerised by the incorporation of Ca2+ ions and energy dispersive X-ray analysis revealed that, in all cases, the Ca:Si ratios were significantly lower than the nominal value of 0.05. -

Understanding of the Mechanisms of Chemical Incompatibility of Ammonium Nitrate by Molecular Modeling
Understanding of the mechanisms of chemical incompatibility of ammonium nitrate by molecular modeling Stefania Cagnina Summary The serious potential consequences of the hazards posed by chemical incompatibility, especially in a large-scale industrial environment, provide motivation for a deeper understanding of the mechanisms of the reactions involved in these phenomena. In this PhD work, two incompatibilities of ammonium nitrate were studied by molecular modeling. Results, in qualitative agreement with the calorimetric experiments, show the potential of the modern computational approaches to establish a clear link between microscopic (molecular) description and macroscopic effects of incompatibilities. Problem addressed Numerous chemical reactants, whenever placed in contact with other products or materials, tend to lead to undesired chemical incompatibility phenomena. Ammonium nitrate (NH4NO3, AN), widely used in the chemical industry as fertilizer component and as an ingredient in explosive mixtures, is known for its long list of incompatibilities (as metals, halides, and organics) [1] and often involved in major accidents (Toulouse, 2001). Indeed, such incompatibilities are known to reduce the runaway temperatures and sometimes increase the reaction enthalpies. In order to prevent the occurrence of those phenomena, which can lead to particularly dangerous situations in an industrial environment, a rapid and accurate identification of the incompatibilities is needed. Until now, experimental studies, Safety Data Sheets (SDSs), chemical compatibility charts and software were the only possible approaches used to study and prevent incompatibilities. Despite their undeniable utility, these methods do not explain exactly how the incompatibility drives the undesired reaction scheme, in terms of thermodynamic data. Therefore, complementary to these approaches, molecular modeling was used in this PhD work to ensure a deeper understanding. -

Effect of a Nitrite/Nitrate-Based Accelerator on the Strength Development and Hydrate Formation in Cold-Weather Cementitious Materials

Abstract: Recently, there has been increased use of calcium-nitrite and calcium-nitrate as the main components of chloride- and alkali-free anti-freezing agents to promote concrete hydration in cold weather concreting. As the amount of nitrite/nitrate-based accelerators increases, the hydration of tricalcium aluminate (C3A phase) and tricalcium silicate (C3S phase) in cement is accelerated, thereby improving the early strength of cement and effectively preventing initial frost damage. Nitrite/nitrate-based accelerators are used in larger amounts than usual in low temperature areas ◦ below −10 C. However, the correlation between the hydration process and strength development in concrete containing considerable nitrite/nitrate-based accelerators remains to be clearly identified.

Chapter 2 EXPLOSIVES
Chapter 2 EXPLOSIVES This chapter classifies commercial blasting compounds according to their explosive class and type. Initiating devices are listed and described as well. Military explosives are treated separately. The ingredi- ents and more significant properties of each explosive are tabulated and briefly discussed. Data are sum- marized from various handbooks, textbooks, and manufacturers’ technical data sheets. THEORY OF EXPLOSIVES In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases that expand rapidly with sufficient force to overcome confining forces; and (4) The energy released by the detonation of explosives produces four basic effects; (a) rock fragmentation; (b) rock displacement; (c) ground vibration; and (d) air blast. A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases. The gases continue to fill and expand the cracks until the gas pressure is too weak to expand the cracks any further, or are vented from the rock. The ingredients in explosives manufactured are classified as: Explosive bases. An explosive base is a solid or a liquid which, upon application or heat or shock, breaks down very rapidly into gaseous products, with an accompanying release of heat energy.
