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.

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:|

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.
