More info

Lead Telluride (PbTe) is a compound of lead and tellurium. It crystallizes in the NaCl crystal structure with Pb atoms occupying the cation and Te forming the anionic lattice. It shows high thermoelectric performance at room temperature. Heeger Materials offers a selection of over 100 high-purity products, including metals, metal oxides, and metal salts, with 99.999% purity or higher.
