LEAD TELLURIDE Chemical Properties,Uses,Production
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.
Chemical Properties
irregular chunks with metal lustre
Uses
In photoconductor cells; in semiconductor research.
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.
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.
General Description
This product has been enhanced for energy efficiency.
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 tube in the assembled cavity, and the synthesis pressure was 4.0 GPa, the temperature was 1200 K. The cooling rate of the sample after stopping the heating was 60 K/s, and the average grain size of PbTe was synthesized to be 1000 nm. The electrical conductivity of the sample was 610-5 -m, and the value of thermal conductivity was 1.4 w/m.k. The sample was synthesized by the use of graphite as the heating tube and chlorite as the insulating tube, and the sample was synthesized by the use of graphite as the heating tube and chlorite as the insulating tube.
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.
