Appearance Monoclinic crystal
Property: Potassium Carbonate is monoclinic crystal, white powder, granular crystal or prill.The relative density is 20428 and the melting point is at 891 degree C. It is easily soluble in water forming a slightly alkaline solution.

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 production alcohol and acetone; and anti-aging agent in rubber production. Its solution is used in boiling and scouring of cotton 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.
Handling and storage:Store in dry ventilated house away from moisture.Don’t store in goods yards or expose to the air.Protect the material from rain when loading and unloading. Be sure to keep from contaminant.Avoid handling and transporting together with acid substances. In the event of a fire,use water as extinguishing agent.
Packing: Plastic woven bag or kraft paper bag inner with plastic bag,in 25/50/500/800/900/1000kg net.
