Detailed Description:

Cas No. :7778-80-5

Potassium Sulphate

Colorless or white orthogonal six-party crystallization or powder

Properties:

Bitter in taste and salty. Density 2.662 g/centimeters 3. Melting point, °C 1069 boiling point 1689 * C, soluble in water soluble in ethanol, acetone and carbon disulfide.

It in water solubility of ammonium sulfate and potassium chloride because of the existence of decreased,

while in fact insoluble in after two compounds of saturated solution.

Application:

mainly applied in glass industry,food industry, medicine and agriculture ect

Used as drugs (e.g. delay evacuant), fertilizer (k about 50%, it is a kind of rapidly-available potassium fertilizer, can make the basal, seeds and non-uniform). Also used for making alum, glass and potash, etc.
