碳酸钾99.0％的98.5%

Property:Potassium Carbonate may be monoclinic crystal, white powder, granularcrystal or prill. The relative density is 2.428 and the melting point is at891 degree C .It is easily soluble in water forming a slightly alkalinesolution. It is insoluble in alcohol and ether. It has strong hygroscopicity.It easily cakes and turns into Potassium Bicarbonate through absorbing carbondioxide when exposed to the air for a long time.CAS RN:584-08-7Specification: Industrial Grade ( GB/T 1587-2000 )INSPECT IONITEMUNITFINE GRADETV GLASSGRADEFIRST GRADEREGULARGRADEPurity(as K2CO3)% Min99.099.098.596.0Chloride(asKCl)% Max0.010.030.100.20Sulphate(asK2SO4)% Max0.010.040.100.15Iron% Max0.0010.0010.0030.010nsolublematter in water% Max0.020.040.050.10Burnt loss% Max0.60.81.001.00Specification: Food Grade (HG2452-93)NSPECT IONITEMUNITSTANDARDPurity(as K2CO3)% Min99.0Chloride(asKCl )% Max0.01Sulphate (asK2SO4)% Max0.01Iron% Max0.001Insolublematter in water% Max0.02Burnt loss% Max0.6Arsenic% Max0.0003HeavyMetal(as Pb)% Max0.002Packing:Plastic woven bag or kraft paper bag inner with plastic bag, in 25/50/500/800/900/1000KG net .Handling and Storage:Store in dry and ventilated house away from moisture.

Be sure to keep the package dry and free from contaminant.Avoid handling and transporting together with acid substances. In the eventof a fire, use water as extinguishing agent.Applications :Potassium Carbonate is used as raw materials in manufacturing electrotube, TV kinescope, computer display. It is applied in optical glassimproving clarity, strength and refractive index. It is also applied inelectrode avoiding electric arc breaking-off during welding. It is used toproduce food additives like potassium sorbate, monopotassium phosphate, etc.Potassium Carbonate is foliar spray fertilizer and a constituent of compoundfertilizer. In dyeing industry, it is used to produce vat dyestuff anddischarge of ice dyeing. It is absorbent removing hydrogen sulfide and carbondioxide; dry powder extinguisher mixed with soda; auxiliary raw material forproducing alcohol and acetone; and anti-aging agent in rubber production. Itssolution is used in boiling and scouring of cotton cloth and wool'sdegreasing. In addition, it is also used in manufacture of printing ink,photograph-drug, polyester, explosives, electroplating, tanning, ceramic,building materials, crystals and medicine.
