Calcium nitrate | Ca(NO3)2 - PubChem

Calcium nitrate soln (0.5, 0.25 M), alone or in coination with sucrose, were toxic to stem and flower (carnation) tissue prior to freezing. Calcium nitrate alone offered no protection at -4 deg C. Flowers pretreated with 0.125 M calcium nitrate appeared translucent or water-soaked after 5 days at -4 deg C.

Calcium carbonate - Essential Chemical Industry

2019-4-26 · Three types of calcium carbonate-containing rock are excavated and used by industry. They are limestone, chalk and dolomite. Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure.
