Calcium nitrate tetrahydrate contains four crystal waters, and every 236g calcium nitrate tetrahydrate contains 72g crystal water. Calcium nitrate does not contain crystal water. Unless it is indicated as anhydrous calcium nitrate, all calcium nitrates on the market are tetrahydrates. Anhydrous calcium nitrate can be used as a dehydrating agent. It is a slightly yellowish white powder. Calcium nitrate tetrahydrate is a white crystal (often with some water droplets on the surface).
Calcium nitrate tetrahydrate has the following effects:
Function OneMainly used as refrigerant, rubber emulsion flocculant, and also used to make other nitrates, fireworks, electron tubes, quick-acting fertilizers, etc.
Function twoIt is a raw material for the manufacture of other nitrates. Used in the defense industry to manufacture explosives. The electronic instrument industry is used to coat the cathode. Light industry is used to make pyrotechnics and incandescent lampshades. Used in agriculture as a quick-acting fertilizer for acid soils. It can also be used as a refrigerant and a flocculant for rubber emulsions.
Function threeAnalytical detection of sulfate and oxalate, preparation of basic medium, electron tube (carbonate coated cathode). Manufacturing incandescent lampshades and other nitrates.
