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
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.
