Physical properties White cubic crystal; hygroscopic; density 2.50g/cm3; melts at 561°C; highly soluble in water; also dissolves in alcohols and acetone. Uses Calcium nitrate is mainly used as a component in fertilizers. Nitrocalcite is the name for a mineral which is a hydrated calcium nitra...
Thermodynamic properties of calcium nitrate are of interest for development of thermodynamic databases, which can be applicable for thermal energy storage technologies. In the present work thermodynamic properties of Ca(NO3)2, i.e. heat capacity ( C p) and enthalpy of fusion, were determined ...
2.2 Chemical Properties white or yellowish deliquescent, hexagonal crystal(s); prepared from nitric oxide and a mixture consisting of calcium ferrate and calcium nitrate; used to inhibit corrosion in lubricants and concrete [MER06] 2.3 Water Solubility Soluble in water, slowly soluble in alcohol ...
In this paper, firstly, fi-tricalcium phosphate (fi-TCP) nanopowders with particle size of 50-70 nm were synthesized using a simple sol-gel route with calcium nitrate and potassium dihydrogenphosphate as calcium and phosphorus precursors, respectively. Then, the porous ceramic scaffold containing 40...

This paper deals with the effect of the leaching process of cement based materials on their mechanical and physical properties. In order to characterize this effect, we have performed experiments on cement paste samples. The leaching process was achieved by the use of a 50% concentrate solution ...
Conclusively, the intrinsic descriptor Φ, consisting of physical parameters obtained conveniently in elemental periodic table, has the predictive capability for H2 storage properties. Fig. 3: The minimum Gibbs free energy change before and after H2 adsorbed on the optimal site of each X-G-Ca ...
The use of KNO3 and Ca(NO3)2 as modelling material, for investigating industrial processes which are especially affected by the thermo-viscous material properties of a substance solidifying in a vitreous manner from a melt, is new. Preferably, the modelling material contains 40-60 wt.% Ca(NO3...
Physical propertiesCalcium carbonate has the molecular formula of CaCO3and the molecular weight of 100.0924 g/mol. It is a common substance found in rock in all parts of the world, and is the main component of the shells of many marine organisms such as snails and conches. It is the main...
2.3 Chemical Properties CALCIUM SULFIDE is OFF-WHITE POWDER 2.4 Physical Properties Calcium sulfide is slightly soluble in water but insoluble in alcohol. It reacts with acids, producing hydrogen sulfide gas.Calcium sulfide is pale yellow to light gray with a bittertaste. It is hygroscopic, produci...
