1. Potassium Carbonate K2CO3 Introduction
Potassium carbonate is a inorganic compound substance with chemical formula K2CO3 and molecular weight of 138.206. It is a white crystalline powder with a density of 2.428g/cm3 and a melting point of 891 ℃. It is easily soluble in water, and the aqueous solution is alkaline. It is insoluble in ethanol. Potassium carbonate has strong hygroscopicity. When exposed to the air, it can absorb carbon dioxide and water, which can be converted into potassium bicarbonate. We have exported potassium carbonate to mainly countries such as Mexico, Kazakhstan, Egypt, etc.

3. Potassium Carbonate K2CO3 Applications
Potassium carbonate is a versatile chemical substance, whose main uses include:
1. Food industry: Potassium carbonate is used as a leavening agent in food, which can improve the color and flavor of food. At the same time, as an alkaline agent and dough improver, it helps to inhibit the sourness of noodles and is suitable for noodle food.
2. Chemical industry: Potassium carbonate is a raw material used in the production of electronic tubes, television tubes, and computer display glass shells. It is also used in the production of optical glass to improve transparency, strength, and refractive index.
3. Pharmaceutical industry: Potassium carbonate is used to produce products such as foam alkali, polyester, electroplating, leather making, ceramics, building materials, crystals, and pharmaceuticals.
4. Agricultural application: Agricultural grade potassium carbonate is a thermal quick acting fertilizer that contains abundant potassium and other trace elements, which can promote plant growth and improve disease and pest resistance. We have several Mexican customers who use potassium carbonate for fertilizer.
5. Other uses: Potassium carbonate is also used as a gas adsorbent, dry powder fire extinguishing agent, rubber anti-aging agent, and has applications in removing carbon dioxide from fertilizer synthesis gas.
4. Functions in Glassware/Glass Making
The application of potassium carbonate in glassware manufacturing is mainly reflected in the following aspects:
1. Lowering the melting point of glass: Potassium carbonate K2CO3 can react with glass materials such as silicon dioxide to form alkali metal silicates with lower melting points, thereby lowering the melting point of glass. This characteristic is particularly important in the glass production process as it helps to reduce manufacturing costs and improve production efficiency.
2. Improving processing performance: As a flux, potassium carbonate K2CO3 can significantly enhance the flowability of glassware, making it more uniform during the manufacturing process. This helps to reduce the occurrence of defects such as bubbles and stripes, and improve the quality of glass products.
3. Adjusting refractive index: Adding an appropriate amount of potassium carbonate K2CO3 can change the refractive index in glassware making, giving it specific optical properties. This characteristic is particularly important in fields such as optical fiber manufacturing, as the performance of optical fibers largely depends on their refractive index and thermal expansion coefficient.
4. Improving corrosion resistance: Potassium carbonate K2CO3 has good resistance to corrosive substances such as acid and alkali, which can reduce the dissolution rate of glass and improve its corrosion resistance. This characteristic is particularly important when manufacturing glassware products that need to withstand corrosive environments, such as glassware.
