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.<\/p>\n
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.
\nCrystal 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.
\nDensity: 8.164g\/cm3
\nMelting point: 905\u00b0C
\nAppearance: white solid
\nSolubility: insoluble in water<\/p>\n
Thermoelectric field: As an excellent thermoelectric material, Lead Telluride is widely used in thermoelectric power generation and refrigeration devices.<\/p>\n
Infrared technology: In the field of infrared detectors and infrared sensors, Lead Telluride materials play a key role.<\/p>\n
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.<\/p>\n","protected":false},"excerpt":{"rendered":"
