Potassium Sulphate Fertilizer
1. Brief Introduction
Potassium sulfate (K2SO4)is a non-flammable white crystalline salt which is soluble in water. The chemical is commonly used in fertilizers, providing both potassium and sulfur.
2.Property
The anhydrous crystals form a double six-sided pyramid, but are in fact classified as rhombic. They are transparent, very hard and have a bitter, salty taste. The salt is soluble in water, but insoluble in solutions of potassium hydroxide (sp. gr. 1.35), or in absolute ethanol. It melts at 1067 °C.
3.Characteristic
Almost no chlorine, sodium and heavy metal . Free liquidity, white crystal powder, soluble in water rapidly. Aqueous solution show weakly acidic, can improve absorption of other cationic (especially trace elements). Can meet the need of potassium of crops, lower salt-chemical index, applicable to all crops and all stages ,including flowering and maturity stages.4. Specification

5.Application
The principal use of potassium sulfate is as a fertilizer.
Potassium sulfate is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback and blast overpressure.
