Potassium Carbonate K2CO3, CAS No 584-08-7 White Granular Potassium Carbonate for Tableware Making
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 Tableware Making
The application of potassium carbonate K2CO3 in tableware making is mainly reflected in the following aspects:
1. Enhancing the hardness and luster of glaze: In the production process of ceramic tableware, potassium carbonate K2CO3 acts as a glass forming agent and participates in the glass reaction in the glaze, which can increase the hardness and luster of the ceramic glaze, making the tableware more durable and beautiful.
2. Adjusting acidity and alkalinity: Potassium carbonate K2CO3 can also serve as a pH regulator in the manufacturing of ceramic tableware, helping to adjust the acidity and alkalinity of the glaze, thereby improving the quality and appearance of the glaze surface.
3. Enhance adhesion and color vividness: During the printing and dyeing process, potassium carbonate K2CO3 acts as a mordant, which can enhance the adhesion and color vividness of dyes, making the appearance of tableware more beautiful.
