Packing: In 20kg/25kg/50kg/500kg/1000kg PP/PE bag
Property:
Colorless and transparent crystals or white powder, relative density 2.109, melting point at 334C. It decomposes at 400C adn turns into potassium nitrite releasing oxygen and then in continous 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't deliquesce in the air. As strong oxidizer, it will burn and explode when meeting with organics releasing irritant gas. If mixed with cabon powder or sulfur, it burns with strong light.
Usage:
Used in compound fertilizer and foliar spray fertilizer for crop and flower;
Applied in TV kinescope glass, glass refining agent and motor light glass:
Fireworks to produce purple flame and black powder in mine, ignition wire and firecracker.
