Lithium telluride

Lithium telluride (Li₂Te) is an inorganic compound of lithium and tellurium. Along with LiTe₃, it is one of the two intermediate solid phases in the lithium-tellurium system.^[3] It can be prepared by directly reacting lithium and tellurium in a beryllium oxide crucible at 950°C.^[4]
