Lead telluride, an inorganic compound with the chemical formula PbTe, is mainly used in the manufacture of thermoelectric converters (coolers, generators, heat sources), infrared detectors, and tunneling diodes.
Chemical composition: PbTe consists of lead (Pb) and tellurium (Te), with lead at +2 valence and tellurium at -2 valence, and its chemical formula is PbTe.
Crystal structure: PbTe has a rock salt (NaCl type) crystal structure, i.e., cubic crystal system, in which lead and tellurium atoms occupy the lattice points of the face-centred cubic lattice respectively.
Density: 8.164g/cm3
Melting point: 905°C
Appearance: white solid
Solubility: insoluble in water
Thermoelectric field: As an excellent thermoelectric material, Lead Telluride is widely used in thermoelectric power generation and refrigeration devices.
Infrared technology: In the field of infrared detectors and infrared sensors, Lead Telluride materials play a key role.
Electronics: PbTe can be used in the manufacture of various electronic devices, such as diodes and transistors. Due to its special electrical properties, PbTe – basic electronic devices in high temperature electronics, high-speed electronics and other special electronic fields have potential applications.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
