Potassium carbonate is an important basic inorganic chemical, pharmaceutical, and light industrial raw material. It is primarily used in the production of optical glass, welding electrodes, electron tubes, television picture tubes, light bulbs, printing and dyeing, dyes, inks, photographic chemicals, sodium silicate, polyester, electroplating, leather tanning, ceramics, building materials, crystal, potassium soap, and pharmaceuticals. It serves as a gas adsorbent, dry powder fire extinguishing agent, and rubber antioxidant. It is also used for the removal of impurities in synthetic gas for fertilizers and can be utilized as a potassium-containing fertilizer. With the continuous development of high-tech applications, the use of potassium carbonate in detergent additives, monosodium glutamate, food, and other fields is increasingly expanding.
