Potassium Sulphate

Short Description:

Potassium sulfate has excellent physical and chemical properties and has been widely used in many fields. Its main uses include serum protein biochemical testing, Kjeldahl nitrogen catalysts, preparation of other potassium salts, fertilizers, medicines, glass, alum, etc. Especially as potash fertilizer, it is widely used in agriculture.

Potassium sulfate is a colorless crystal, with low moisture absorption, not easy to agglomerate, good physical state, convenient to apply, and is a good water-soluble potassium fertilizer. Potassium sulfate is also a physiological acid fertilizer in chemistry.

Improved lodging resistance

Potassium sulfate is a good water-soluble potassium fertilizer because of its low hygroscopicity, difficulty in caking, good physical properties and convenient application.Rational application of potassium sulfate in crops can improve the lodging
resistance ability of crops, increase grain weight, improve crop quality, reduce pests and diseases, and increase crop yield and income.

Potassium sulphate potassium sulphate is a kind of high quality and efficient potassium fertilizer without chlorine, especially in the planting industry of chlorine-sensitive crops such as tobacco, grape, beet, tea tree, potato, flax and various fruit trees.Potassium sulfate is a chemical neutral, physiological acid fertilizer, suitable for a variety of soils (excluding flooded soil) and crops.

More than 98% industrial potassium sulfate is the basic raw material for the manufacture of various potassium salts such as potassium carbonate and potassium persulfate.The dye industry is used as an intermediate.Perfume industry is used as auxiliaries. In addition, potassium sulfate is also used in the industrial glass, dyes, spices and so on.

In agriculture: Potassium sulfate is a commonly used potash fertilizer in agriculture, and its potassium content is about 50%.

In dustry: Potassium sulfate is a basic raw material for producing various potassium salts such as potassium carbonate and potassium persulfate.
The glass industry is used as a sinking agent.
The dye industry is used as an intermediate.
Spice industry used as additives.
Potassium sulfate is used as an additive in electroplating, acting as a conductive salt and as an aid.

In food industry: The food industry is used as a general additive.

Potassium chloride usually is white or light yellow crystalline, sometimes with iron salt to red. KCL has good physical properties, small moisture absorption, soluble in water, was chemically neutral reactions are physiological acidic fertilizer.

Slender colorless diamond or cubic or white crystalline powder of small particles, like the appearance of salt; no smell, taste salty, soluble in water, soluble in glycerine, slightly in ethanol.

1) K fertilizer for agriculture (to total potassium content of 50-60%), is fast enough for basal and top dressing. However, in saline or potatoes, sweet potatoes, sugar beet, tobacco and other crops avoid application of chloride.

2) Industrial raw materials for the manufacture of other potassium salts. 

3)  Medical care for the prevention of potassium deficiency disease. 

4) Nutritional sulpplements; gelling agent; on behalf of the salt and salt can be used as agricultural products, aquatic products, livestock products, fermentation products, spices, canned and convenience food flavoring agent. Also used to strengthen the potassium(electrolyte used for the body) prepared athlete drinks. Gel effect can be enhanced. 

[Storage & transportation] Stored in dry, cool airiness place, far away from heat, avoid insolation, sign with no moisture and no insolation

Use in 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.

Used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback and blast overpressure.

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

Colorless trapezius or six-party crystals or powder, but industrial more tan-white. Bitter in taste and salty. Density 2.662 g/centimeters 3. Melting point, ℃ 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.

Direct Application, NPK and NK granulation or Ammoniation, NPK and NK Bulk blending, liquid and suspension fertilizers, fertigation (Spinkler, mini sprinkler and Drip irrigation), foliar sprays, foliar NPK fertilizers, starter and transplant solutions, winter hardener, winter breaking dormancy sprays, flowering inducement sprays.

Potassium Sulphate use for making of mud chemicals in oil and gas Industries due to low chloride percentage.

Leading international feed-producers choose our well-proven potassium sulphate for fortifying cat and dog food as well as chicken feed with potassium. The mineral potassium is one of the most important electrolytes in the body, and is essential for cell function. Potassium takes on several functions in the metabolism, for muscle activity and for nerve function. As an alternative to sodium, potassium is particularly important in pet food. It secures a balanced nutrition and can help to prevent cardiovascular diseases. For farm animals, potassium is used to prevent heat stress. As the body is not able to store it, a sufficient supply of potassium through the daily feed ration is needed.
