Used in the production of soap and glass, where it acts as a flux to lower melting temperatures. Commonly employed in the manufacturing of fertilizers to supply potassium, an essential nutrient for plant growth. Serves as a buffering agent in the food industry, particularly in cocoa processing and wine production, to adjust acidity. Utilized in the synthesis of other potassium compounds and in some fire extinguishers as a drying agent. Also found in traditional dyeing processes and as an alternative to sodium hydroxide in certain cleaning formulations due to its milder alkalinity.
