Industrial Grade Potassium Carbonate

Industrial grade potassium carbonate is a white crystalline powder with a density of 2.428g/cm and a melting point of 891 ℃. Soluble in water and alkaline aqueous solution, insoluble in ethanol, acetone and ether. It has strong hygroscopicity. When exposed to air, it can absorb carbon dioxide and water and convert it into potassium bicarbonate. Therefore, it should be sealed and packaged.

  • Product name Industrial grade potassium carbonate
  • Molecular formula K2CO3
  • Molecular weight 138.206
  • CAS NO. 584-08-7
  • HS CODE 28364000

INTRODUCTION

Industrial Grade Potassium Carbonate is an important inorganic chemical raw material with a wide range of applications.
Technical grade potassium carbonate is mainly used in the manufacture of potassium glass, potassium soap and other inorganic chemicals. It is also used to remove hydrogen sulphide and carbon dioxide from industrial gases, helping to purify the industrial environment. Potassium carbonate also plays an indispensable role in the manufacture of welding electrodes and inks, as well as in the printing and dyeing industry. Potassium carbonate is also used as an additive in the manufacture of speciality glasses, such as high-temperature-resistant glass and optical glass, and contributes to energy savings in glass production. It is also a raw material for the production of many high-grade organic fertilisers, which help to improve crop yields and quality. In medicine, potassium carbonate is used as a drug neutraliser to help balance the pH level in the body. In the textile industry, it is used in the catalytic processing of dyestuffs and fabrics and in the fireproofing of textile substrates.
Industrial potassium carbonate is a corrosive substance, irritating to the skin and eyes and damaging to the respiratory tract. Therefore, it is necessary to wear protective clothing, masks and goggles during operation and use, and avoid direct contact as much as possible. Industrial potassium carbonate should be stored in a dry, ventilated and cool place, away from ignition sources and other flammable objects.
