General description
This product aligns with one or more of the 12 Principles of Green Chemistry Find details here.
Lead telluride (PbTe) has a cubic rocksalt crystal structure which undergoes transition at high pressures to an orthorhombic structure.1 PbTe is a thermoelectric material, oxidation in air has been reported. 2
Application
Lead(II) telluride (PbTe) is a narrow bandgap semiconductor with good electrical properties. It is a thermoelectric material with thermal conductivity of ~2 Wm−1K−1 at 300 K, which can be used in thermoelectric power generation and energy conversion.
