2.dolomite- a light colored mineral consisting of calcium magnesium carbonate; a source of magnesium; used as a ceramic and as fertilizer bitter spar atomic number 12,magnesium,Mg- a light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs ...
The acetylene is the base material of a great number of important chemicals for the organic industrial chemistry. The pure calcium carbonate occurs in two crystalline forms: calcite, hexagonal shaped, which possesses birrefringent properties, and aragonite, rhombohedric. The natural carbonates are ...
Among the most common calcium minerals are the two crystalline forms of calcium carbonate-calcite and aragonite (CaCO 3 , limestone is primarily calcite), calcium sulfate (the dehydrated form, CaSO4 , is anhydrite; the hydrated form, CaSO4.2H2O, is gypsum), calcium magnesium carbonate (CaMg(CO...
Calcium is not found free in nature, but calcium compounds are common. Some of the most common compounds found on Earth are limestone (calcium carbonate - CaCO3), gypsum (calcium sulfate - CaSO4·2H2O), fluorite (calcium fluoride - CaF2) and apatite (calcium fluorophosphate - CaFO3P or cal...
