Potassium Carbonate
Product Overview:
CAS #: 584-08-7
Potassium carbonate is used across glass, fertilizer, food, feed, and textile manufacturing applications. It is commonly employed in glass and ceramics manufacturing as a fluxing agent that lowers melting temperatures and improves glass clarity. Additionally, it serves as a potassium source in fertilizer production and as a rumen buffer in dairy cattle feed formulations, helping maintain proper rumen pH and supporting potassium supplementation during heat stress. Potassium carbonate is also utilized in food processing, including cocoa alkalization for chocolate manufacturing and as a leavening aid in certain baked goods. Furthermore, it finds applications in textile dyeing and finishing operations as a pH-adjusting agent.
