| Hazard Information | Back Directory | [Chemical Properties]
irregular chunks with metal lustre | [Chemical Properties]
Lead telluride, PbTe, forms white cubic crystals, sp gr 8.16, and has a hardness of 3 on the Mohs’ scale. It is very slightly soluble in water, melts at 917 °C, and is prepared by melting lead and tellurium together. Lead telluride has semiconductive and photoconductive properties. | [Uses]
In photoconductor cells; in semiconductor research. | [Uses]
In semiconductor research, photoconductor cellsLead(II) telluride is used as an infrared detector material. It is also used in spacecraft power applications. Further, it is used in infrared detection, imaging and in solar cells. In addition, it acts as a semiconductor and photoconductor in the form of single crystals. | [Uses]
Lead telluride is used in pyrometry, in heat-sensing instruments such as bolometers and infrared spectroscopes, and in thermoelectric elements to convert heat directly to electricity. Lead telluride is also used in catalysts for oxygen reduction in fuel cells, as cathodes in primary batteries with lithium anodes, in electrical contacts for vacuum switches, in lead-ion selective electrodes, in tunable lasers, and in thermistors. | [General Description]
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here. | [Synthesis]
The high-purity Pb powder and Te powder were mixed according to the chemical dosage ratio (1:1), and the samples were loaded into the high-pressure cavity after powder pressure molding. Graphite was used as the heating tube and chlorite as the insulating | [Structure and conformation]
The space lattice of PbTe belongs to the cubic system, and its rock salt structure has a lattice
constant of a=0.317 nm. |
