Potassium Carbonate(K2CO3)
CAS No.: 584-08-7
Item Tech. Grade First Grade
K2CO3 99%min 98.5%min
Chloride(kCl) 0.03%max 0.1%max
Sulph(K2SO4) 0.04%max 0.1%max
Iron 0.001%max 0.003%max
Water Insoluble 0.04%max 0.05%max
Loss of burning 0.8%max
Characteristics:
Appearance: 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.
Usage:
Widely used as raw material in manufacturing electro tube, TV kinescope, computer display, applied in optical glass improving clarity, strength and refractive index, applied in electrode avoiding electric arc breaking-off during welding.
Used to produce food additives like potassium sorbate, monopotassium phosphate, etc. It 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 anti-aging agent in rubber production, its solution is used in boiling and scouring of cotton cloth and wool's degreasing.
Used in manufacture of printing ink, photograph-drug, polyester, explosives, electroplating, tanning, ceramic, building materials crystals and medicine
Storage:
Store in dry and 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 the package dry and free from contaminant. Avoid handing and transporting together with acid substance. In the event of a fire, use water as extinguishing agent.
