Description and Uses
Potassium chloride (KCl) is a metal halide salt that is used in a variety of areas. The dominant application of potassium chloride is to serve as a fertilizer, which offers potassium to plants and prevents them from certain diseases. Besides, it can be applied in food and medical industry. As a treatment for hypokalemia, potassium chloride pills are taken to balance the blood's potassium levels and prevent potassium deficiency in the blood. In food industry, it serves as a electrolyte replenisher and a good salt substitute for food, as well as a firming agent to give consistent texture to food, thus to strengthen its structure.
About 4-5% of potash production is used in industrial applications (UNIDOIFDC, 1998). In 1996, the world supply of industrial grade potash was close to 1.35 Mt K2O. This industrial material is 98-99% pure, compared with the agricultural potash specification of 60% K2O minimum (equivalent to 95% KCl). Industrial potash should contain at least 62% K2O and have very low levels of Na, Mg, Ca, SO4 and Br. This high-grade potash is produced by only a few producers in worldwide.
Potassium hydroxide (KOH), also known as caustic potash, is the largestvolume K product for non-fertilizer use. It is produced by the electrolysis of industrial KCl and is widely used for manufacturing soaps, detergents, grease, catalysts, synthetic rubber, matches, dyes and insecticides. Caustic potash is also as a liquid fertilizer and as an ingredient in alkaline batteries and photographic film processing chemicals.
Potassium hydroxide is a raw material in the production of various K salts, mainly K carbonates, and also citrates, silicates, acetates, etc. Potassium carbonate confers excellent clarity to glass thus is used for most fine optical lenses, eyeglasses, fine crystal, glassware, chinaware and TV tubes. Potassium bicarbonate is used largely in the food and pharmaceutical industries.
Potash-derived compounds and salts are also used in the production of metal fluxes, cured meats, tempered steel, paper fumigants, case hardened steel, bleaching agents, baking powder, cream of tartar and beverages. Worldwide, industrial KCl is estimated to be used as follows: detergents and soaps, 30-35%; glass and ceramics, 25-28%; textiles and dyes 20-22%; chemicals and drugs, 13-15%; and other uses, 7-5% (UNIDO-IFDC, 1998).
