Product Overview
Potassium Bicarbonate (chemical formula: KHCO₃) is a white, odorless crystalline powder used in a wide range of industries. It is a potassium-based salt of carbonic acid and serves as a mildly alkaline compound with excellent solubility in water. It decomposes upon heating to form potassium carbonate, carbon dioxide, and water.
It is commonly used as a leavening agent, fire suppressant, nutritional supplement, and fungicide, and is widely accepted in food, agriculture, and industrial sectors.

Production Process
Potassium Bicarbonate is typically produced via a reaction between potassium carbonate (K₂CO₃) and carbon dioxide (CO₂) under controlled conditions:
K₂CO₃ + CO₂ + H₂O → 2KHCO₃
This method ensures high purity and minimal by-products. The product is then crystallized, dried, and milled to the desired particle size.
