Application

Descriptions:

  • Potassium carbonate (K2CO3) is a white salt, also called Potash and pearl ash.

  • Potassium carbonate is soluble in water, which forms a strongly alkaline solution.

  • Potassium carbonate is deliquescent, often appearing a damp or wet solid.

  • Potassium carbonate is dissolved alkaline, hygroscopicity strong, and easy to caking.

Uses:

  • Potassium Carbonate is an important foliar spray fertilizer and a constituent of compound fertilizer.

  • It is used to produce food additives like potassium sorbate, monopotassium phosphate, etc.

  • It is used as raw materials in manufacturing electro tube, TV kinescope, and computer display.

  • It is applied in electrode avoiding electric arc breaking-off during welding.

  • It is applied in optical glass improving clarity, strength and refractive index.

  • In dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing.

  • Its solution is used in boiling and scouring of cotton cloth and wool's degreasing.
