Product Feature:
potassium nitrate is colorless crystal or white power. It is easily soluble in the water and the liquid ammonia but insoluble in anhydrous alcohol. It can not deliquesce in the air.As strong oxidizer, it will burn and explode when mixing with organics.
Applications: Supplying Nitrogen and Potassium as fertilizer. It is mainly applied in making fireworks and black powder; bulb glass shell, optical glass, kinescope glass shell; salt bath of metal heat treatment; Ceramic glaze; cigarette paper and so on.
It is mainly applied in TV glass, glass refining agent and motor light glass; compound fertilizer and foliar spray fertilizerl fireworks and black pounder; drugs and catalyzer; ceramic and enamel; salt both of heat treatment, cigarette paper; concentrating agent etc.
Considerations:
The operator should wear a protective mask, protective gloves, wear work clothes. To prevent inhalation of calcium nitrate dust, respiratory protection.
