Calcium nitrate(used for agriculture)

1.Name:Calcium nitrate

　　Molecular formula :Ca（NO₃）.₄H₂O

　　Formula weight:236.149

2.Property:

　　white powder crystal, soluble in water,density:1.896, decompose at about 40,while being heated up to 150,it will 　

　　completely dehydrate and turn into anhydrous calcium nitrite,when temperature up to 500, it will decompose into

　　calcium nitrite and oxygen, if the teprature continue to go up,it will eventually become calcum oxide and nitrogen
　　oxide,it is freely soluble in methanol,alcohol,acetone,methy acetate and liquid ammonia. It is oxidizer,it is liable to
　　deliquesce in the air.

3. Usage:

　　(1) agricuture:it is a new high efficiency compound fertilizer which can provide N and quick result Ca,it has been widely
　　used in greenhouse and large acreage farmland.

　　(2) industry: it is used for refrigerant,cement antifreezer,bonderite of steel industry,making fireworks and other nitrate.
