CAS 584-08-7 Potassium Carbonate Powder, White Granular Potassium Carbonate K2CO3 for Ceramics
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. Potassium carbonate used in agricultural industry
As a potassium fertilizer, potassium carbonate provides plants with
essential potassium elements, which play a crucial role in nutrient
absorption, biochemical metabolism, and adaptability to the
environment. Potassium carbonate fertilizer also has the
characteristic of good water solubility, which can quickly provide
plants with the necessary potassium element and release carbon
dioxide (CO2), enhancing crop photosynthesis.
2. Potassium carbonate used in glass Industry
At high temperatures, glass is prone to softening and deformation.
Potassium carbonate can increase the softening temperature of
glass, giving it better thermal resistance. This is because
potassium carbonate can decompose at high temperatures, producing
CO2 and K2O, which can form more stable compounds with SiO2 and
other oxides, thereby increasing the melting point and softening
temperature of the glass.
3. Potassium carbonate used in glaze industry
Potassium carbonate can lower the melting point of glaze, promote
its melting and flow, make the glaze smoother and more delicate,
thereby improving the quality of the glaze. In addition, potassium
carbonate can also reduce the shrinkage rate and cracking of glaze,
increase the strength and toughness of the glaze layer.
4. 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. Potassium Carbonate K2CO3 Functions in Ceramics
The main functions of potassium carbonate in ceramics include promoting sintering, strengthening grain boundaries, and reducing porosity. The addition of potassium carbonate can lower the sintering temperature of ceramics, accelerate the diffusion and bonding between ceramic particles, thereby reducing pores and defects in ceramics, and improving the density and hardness of ceramics. In addition, potassium carbonate can also alter the grain boundary structure of ceramics, making them clearer, continuous, and uniform, thereby improving the hardness and flexural strength of ceramics.
The specific application effect of potassium carbonate in ceramics
Promoting sintering: Potassium carbonate K2CO3 plays a promoting role in the sintering
process of ceramics, reducing the sintering temperature,
accelerating the diffusion and bonding between ceramic particles,
reducing pores and defects, and improving the density of ceramics.
Grain boundary strengthening: The addition of potassium carbonate K2CO3 can change the grain boundary structure of ceramics, making it
clearer, continuous, and uniform, thereby improving the hardness
and flexural strength of ceramics.
Reduce pores: Potassium carbonate K2CO3 can react with other raw materials to generate gases or volatiles,
effectively eliminating pores in ceramics and improving their
density and hardness
