Potassium Carbonate
Product Name: Potassium Carbonate
Molecular formula: K2CO3
Molecular weight: 138.2
CAS NO.: 584-08-7
HS CODE: 28364000
Property: 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.

Handling and 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
handling and transporting together with acid substances. In the
event of a fire, use water as extinguishing agent.
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 anti-aging 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.
