Product Description
Name: Potassium Nitrate CAS No: 7757-79-1 Molecular formula: KNO3
Appearance: White crystal powder and granular
Product Feature
Property: Potassium Nitrate 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.
