Calcium Nitrate
1. Name: Calcium nitrate
Molecular formula Ca (NO3）2.4H2O
Molecular weight 236.149
2. Properties:White powdery crystal, easily soluble in water, relative density 1.896, begins to decompose at about 40°C; when heated to 150°C, it loses all crystal water and forms anhydrous calcium nitrate, At 500°C, calcium nitrate
decomposes to form calcium nitrite and release oxygen; with further heating, it forms calcium oxide and nitrogen oxides. It is easily soluble in methanol, ethanol, acetone, methyl acetate, liquid ammonia, and nitric oxide.
Calcium nitrate is hygroscopic and easily deliquesces in the air.
3. Purpose:
①Industry: used as refrigerant and cement antifreeze, phosphating agent in the steel industry.
②Agriculture: This is a new compound fertilizer containing nitrogen and calcium. It has fast fertilizer effect. It can quickly replenish calcium and nitrogen when washed with water or sprayed on foliage. It is widely used in greenhouses and large areas.
farmland.
farmland.
