Characteristic
Lead telluride is a compound of lead and tellurium (PbTe). It crystallizes in the NaCl crystal structure with Pb atoms occupying the cation and Te forming the anionic lattice. It is a narrow gap semiconductor with a band gap of 0.32 eV.
Chemical formula：PbTe
CAS#:1314-91-6
Molar mass：334.80 g/mol
Appearance：gray cubic crystals.
Density：8.164 g/cm3
Melting point：924 °C (1,695 °F; 1,197 K)
Solubility in water：insoluble
Band gap：0.25 eV (0 K)
0.32 eV (300 K)
Electron mobility：1600 cm2 V−1 s−1 (0 K)
6000 cm2 V−1 s−1 (300 K)
Crystal structure：Halite (cubic), cF8
Application
PbTe has proven to be a very important intermediate thermoelectric material.
In addition, PbTe is also often alloyed with tin to make lead tin telluride, which is used as an infrared detector material.
