|Certilicate:||ISO 9001||Type:||Potassium Nitrate|
Potassium nitrate granular for industry and agriculture fine grade
1. Potassium nitrate is colorless transparent rhombic crystal or white powder. Relative density is 2.109 g/cm3 and melting point 334℃. At about 400℃, it will decomposite and release oxygen and change into potassium nitrate. If continue to heat, it will generate potassium oxide.
2. Potassium nitrate is well soluble in water, liquid ammonia and glycerin. Insoluble in absolute ethyl alcohol and ether. Not easy to deliquesce in the air.
3. Potassium nitrate is a strong oxidant which will burn and explode when contact with organic matters and release toxic gas with pungent odor. It will release strong light and burn when heated with carbon powder or sulfur.
|Inspection Item||Unit||Fine Grade||Industial Grade||Agricultural Grade||Ceramic Grade|
|Appearance||White Crystal Powder|
White fine crystal. Some are light gray or buff. The relative molecular weight is 84.99 and density is 2.257. It's easy to be deliquescence and to dissolve in water and liquid ammonia, but only a little can dissolve in ethanol and glycerin. The melting point is 271°C. And decomposition temperature is 380°C. Its decomposition products are sodium nitrite and oxygen. If heated to higher temperature, it will be decomposed into the mixed gas of oxygen, azote and oxynitride. It has the strong oxidizing property and can cause the inflammation and explore while mixed with organics, sulfur and sulfite etc.
Potassium Nitrate is colorless crystal or white powder. 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. It is mainly applied in TV glass, glass refining agent and motor light glass;compound fertilizer and foliar spray fertilizer; fireworks and black pouder; drugs and catalyzer; ceramic and enamel;salt both of heat treatment, cigarette paper; concentrating agent;etc.
