Property: white powder crystal, soluble in water,density:1.896, decomposed 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 temprature continue to go up,it will eventually become calcium 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.
Usage:
(1) agriculture: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.
