'''Beryllium telluride''' (BeTe) is a chemical compound of [[beryllium]] and [[tellurium]]. It is a crystalline solid with [[face centred cubic]] symmetry, [[lattice constant]] 0.5615 [[nanometer|nm]]. The density is 5.1 g/cm<sup>3</sup>. The CAS number is {{CASREF|CAS=12232-27-8}}.
It is a [[semiconductor]] with a large [[band gap|energy gap]] of around 3 eV.
Toxic [[hydrogen telluride]] gas is evolved on exposure to water.
Toxicity is unknown, but both beryllium and tellurium are toxic.
