Physical and Chemical Properties:

Potassium sulfate (in British English potassium sulphate (SOP), also called sulphate of potash, arcanite, or archaically known as potash of sulfur) is the inorganic compound with formula K2SO4. It is a white water-soluble solid. It is commonly used in fertilizers, providing both potassium and a source of sulfur.

Potassium Sulphate (SOP) is straight potassic fertiliser which is chloride (Cl) free and has low salt index. It is also known as fertilizer for improving quality and is applied to crops in open field as well as under protected cultivation.

Grade Standard:  

Note: The above specification is satisfy with GB/T20406-2017, also accord with European and American Standards.We can accept the Third part test.Such as BV,SGS etc.

Application: 

The dominant 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 overpressure.

It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.

Potassium sulfate can also be used in pyrotechnics in combination with potassium nitrate to generate a purple flame.

Potassium sulfate is used as a conductivity enhancer in the preparation of antistatic formulations. It is better known as a plant nutrient. It is soluble in water (120 g/L) yielding two ions in solution: potassium (K+) and sulfate (SO42−).20
