Chi tiết

Properties: Potassium Nitrate - Kali nitrat - KNO3

Potassium Nitrate is colorless crystal or white powder. It is easily soluble in 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.

Uses:
It is mainly applied in TV glass, glass refining agent and motor light glass; compound
fertilizer and foliar spray fertilizer; fireworks and black powder; drugs and catalyzer;
ceramic and enamel; salt both of heat treatment, cigarette paper, concentrating agent;
as chromogen agent, preserving agent in food industry.

Packing : in 25/1000kg net each PP/PE bag, or according to customer's requirement.

Application

Fertilizer	l Used in fertilizers, as a source of nitrogen and potassium-two of the macro nutrients for plants.
Oxidizer	l Used in black powder rocket motors, but also in combination with other fuels like sugars in "rocket candy". l Used in fireworks such as smoke bombs, made with a mixture of sucrose and potassium nitrate. l Added to pre-rolled cigarettes to maintain an even burn of the tobacco and is used to ensure complete combustion of paper cartridges for cap and ball revolvers.
Food preservation	l It has been a common ingredient of salted meat, such as charcuterie and the brine used to make corned beef.
Fire extinguishing	l It is the main solid particle component of condensed aerosol fire suppression systems.
Tree stump removal	l It is the main component (usually about 98%) of tree stump remover, as it accelerates the natural decomposition of the stump by supplying nitrogen for the fungi attacking the wood of the stump.
Heat treatment of metals	l It is commonly used in the heat treatment of metals as a solvent in the post-wash.
Pharmacology	l It was added in toothpastes for treating sensitive teeth. l It was used for treating asthma as well as arthritis. l It combats high blood pressure and was used as a hypertensive.
