Chemical database: 22. Potassium chloride

Potassium chloride (KCl) is an inorganic compound without a specific smell or taste. At standard conditions, it comes in form of small colorless crystals. Density = 1.98 g/cm3. Melting point = 770°C. Boiling point = 1420°C (sublimes). It can be found in the natural environment as well, in form of various minerals (e.g. sylvite). Potassium chloride is mostly used in the production of mineral fertilizers, in the production of various substances like potassium hydroxide or pure potassium. It is also used in medicine and in the food industry as a substitute for table salt (sodium chloride).

Potassium chloride can be found or ordered from certain drugstores/pharmacies. In larger amounts, potassium chloride can be ordered from companies that sell chemicals to various types of industries. Potassium chloride can also be found in products that are used as a substitute for table salt. However, such products don't contain pure potassium chloride, but often other compounds as well.
