Potassium Carbonate Chemical Powder for Construction

Potassium Carbonate may be
monoclinic crystal, white powder, granular
crystal or prill. The relative density is 2.428
and the melting point is at 891 degree C .It is easily soluble in water forming a slightly alkaline solution. 

It is insoluble in alcohol and ether. It has strong hygroscopicity. It easily cakes and turns into Potassium Bicarbonate 

through absorbing carbon dioxide when exposed to the air for a long time.

Applications :

Potassium Carbonate is used as raw materials in manufacturing electro tube, TV kinescope,

computer display. It is applied in optical glass improving clarity, strength and refractive index. It is also

applied in electrode avoiding electric arc breaking-off during welding. It is used to produce food additives like potassium sorbate, monopotassium phosphate,

etc. Potassium Carbonate is foliar spray fertilizer and a constituent of compound fertilizer. In dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing. It is absorbent removing hydrogen sulfide

and carbon dioxide; dry powder extinguisher mixed with soda; auxiliary raw material for producing alcohol

and acetone; and antiaging agent in rubber production. Its solution is used in boiling and scouring of cotton cloth and wool's degreasing. In addition, it is also used in manufacture of printing ink, photograph-drug, polyester, explosives, electroplating, tanning, ceramic, building materials, crystals and medicine.
