Good feedback wholesale k2co3 potassium carbonate powder price
Introduction
Potassium carbonate (K2CO3) is a white salt, also called Potash and pearl ash. Potassium
carbonate soluble in water (insoluble in alcohol), which forms a strongly alkaline solution.
It can be made as the product of potassium hydroxide's absorbent reaction with carbon
dioxide. It is deliquescent, often appearing a damp or wet solid.
Application
1. It is applied in optical glass improving clarity, strength and refractive index.
2. It is also applied in electrode avoiding electric arc breaking-off during welding.
3. It is used to produce food additives like potassium sorbate, monopotassium phosphate, etc.
4. Potassium Carbonate is foliar spray fertilizer and a constituent of compound fertilizer.
5. In dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing.
6. 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.
7. Its solution is used in boiling and scouring of cotton cloth and wool's degreasing.
8. In addition, it is also used in manufacture of printing ink, photography drug, polyester, explosives, electroplating, tanning, ceramic, building materials, crystals and medicine.
