Caustic Potash
Potassium hydroxide (KOH), commonly known as caustic potash, is the largest-volume potassium chemical for non-fertilizer use. It is produced by the electrolysis of potassium chloride with membrane cell technology. Co-products are chlorine and hydrogen.
Applications
A strong alkali, Potassium Hydroxide is available in both liquid and dry forms. It has applications in fertilizers, batteries, soaps and detergents, specialty glasses and other industrial operations. It also serves as a chemical intermediate for dyes, pharmaceuticals and photographic chemicals.
