Potassium telluride (K2Te)

​Potassium telluride (K₂Te) is an inorganic compound composed of potassium and tellurium, classified as a telluride. It typically appears as a pale yellow powder that turns gray upon exposure to air. The compound has a molar mass of 298.64 g/mol and a melting point of approximately 874 °C. ​When exposed to air, potassium telluride undergoes oxidation, leading to the formation of potassium hydroxide (KOH) and elemental tellurium. It can react with moisture and air.

Potassium telluride (K2Te) is stable in air but decomposes on heat to release toxic hydrogen telluride gas. Like rubidium telluride and cesium telluride, it can be used as an ultraviolet detector in space, as a photosensitive agent in some photosensitive silver salt photographic materials, and as a semiconductor material for electronic devices. The crystal structure of Potassium telluride (K2Te) is similar to that of other tellurides with antifluorite structure. Tellurium reacts with melted potassium cyanide to form potassium telluride. It can also be produced by the direct combination of potassium and tellurium, the reaction is usually carried out in liquid ammonia solvent, the reaction equation is: 2K + Te = K2Te Adding potassium telluride to water and letting the filtrate sit in the air will REDOX with oxygen to form potassium hydroxide and elemental tellurium.
