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. ==External links== * [http://www.matweb.com/search/SpecificMaterial.asp?bassnum=DSEM11 Matweb] [[Category:Beryllium compounds]] [[Category:Tellurides]] [[Category:Semiconductor materials]] {{inorganic-compound-stub}} [[ar:تيلوريد بيريليوم]]
