Potassium nitrate
Molecular formula: KNO3
CAS: Potassium nitrate
Appearance: Colorless crystal or white powder
Properties:
The relative density 211, melting point degree 330. Soluble in water, but soluble in ethanol and glycerin, insoluble in anhydrous alcohol. Have strong oxidizing.
1) purity: 99.8% , 99.4% tech grade
2) purity: 97.5% agri. Grade
3) without anti-caking agent
4) low price
Properties: It is colorless and transparent rhombic crystals or white powder. The relative density is 2.109 and the melting point is at 334° C. It decomposes at 400° C and turns into potassium nitrite releasing oxygen and then in continuous heat turns into burnt potash. It is highly soluble in water, liquid ammonia and glycerine but insoluble in anhydrous alcohol and diethyl ether. It can not deliquesce in the air. As strong oxidizer, it will burn and explode when meeting with organics releasing irritant gas. If mixed with carbon powder or sulfur, it burns with strong light.
Protection:
Operators should wear protective smock including respirator and rubber gloves, etc. Be careful not to inhale the powder of potassium nitrate to protect respiration apparatus.
Handling and Storage: Store in a cool, ventilated and dry house, away from moisture, heat or kindling. Avoid mixing with organic compound or sulphur or reducer during storage and transportation in case of explosion. Protect the material from the sun and rain during transportation. Carefully load and unload in case of crash.
