Potassium (K) Metal

Potassium is silvery-white, soft, and light. It is the second lightest-known metal besides lithium. It has a low melting point and good conductor of heat and electricity. Potassium imparts a lavender color to a flame, and its vapor is green. It is usually not found in its native form in nature but in minerals in igneous rocks, shale, and sediment.
It is one of the most electropositive metals, so it, like other alkali metals, is extremely reactive, decomposing rapidly in water, where it can ignite spontaneously.

Purity: 98-99.5%
Typical Applications

Potassium forms alloys with many metals, but only the alloy obtained with sodium is of interest in the technology of nuclear reactors. The greatest demand for potassium compounds is in fertilizers. Potassium carbonate is used in glass manufacturing. Potassium hydroxide is used as an industrial reagent to make detergent and liquid soap. Potassium chloride is widely used in pharmaceuticals and saline drips.
