Potassium telluride is an inorganic compound with a chemical formula K2Te. It is formed from potassium and tellurium, making it a telluride.[2] Potassium telluride is a white powder. Like rubidium telluride and caesium telluride, it can be used as an ultraviolet detector in space. Its crystal structure is similar to other tellurides, which have an anti-fluorite structure.
