White Granular Potassium Carbonate K2CO3 Price, Purity 99.5% Potassium Carbonate Used in Welding Rod
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 Welding Rod
Potassium carbonate K2CO3 plays two main roles in welding electrodes: as a flux and to enhance current conduction.
Firstly, the role of potassium carbonate as a flux:
Lowering melting point: Potassium carbonate K2CO3 can lower the melting point of welding electrodes, making them easier to melt and integrate with the welded material.
Improving weld quality: Potassium carbonate K2CO3 can reduce the formation of pores and improve the flowability of the solution, which is beneficial for the formation of welds and the improvement of welding quality.
Secondly, the effect of potassium carbonate on enhancing current conduction:
Improving conductivity: Potassium carbonate K2CO3 can enhance the conductivity of the welding arc, allowing the current to flow more stably through the handle and electrode, resulting in a more stable welding effect.
Control arc shape: Potassium carbonate can increase the excitation current of the arc, making it more stable and regular in shape, thereby controlling the shape and width of the weld seam.
Through these effects, the application of potassium carbonate in welding electrodes significantly improves welding quality and efficiency.
