Potassium Sulphates By Shree Laxmi Corporation

Potassium sulfate is a non-flammable white crystalline salt which is soluble in water. The chemical is commonly used in fertilizers, providing both potassium and sulfur.
Formula: K2SO4
Molar mass: 174.259 g/mol
Density: 2.66 g/cmA
Melting point: 1,069 A C
Boiling point: 1,689 A C
Soluble in: Water
Application:
The principal use of potassium sulfate is as a fertilizer. K2SO4 does not contain chloride, which can be harmful to some crops. Potassium sulfate is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require potassium sulfate for optimal growth if the soil accumulates chloride from irrigation water.
The crude salt is also used occasionally in the manufacture of glass. Potassium sulfate is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback and blast over pressure.
