Antimony Telluride Powder

Antimony Telluride Powder

Antimony telluride powder has been widely used as a low temperature thermoelectric material for many years, because of its relatively high ZT parameter value. These good thermoelectric properties of Sb2Te3 powder are due to its crystallographic structure. Thanks to this crystallography, it is also possible to control the macroscopic properties of the compound by structuring the polycrystalline material. Spark plasma sintering (SPS), when used to densify thermoelectric materials, can prevent grain size growth and increase ZT by decreasing thermal conductivity. The process can be used to obtain high-density samples that can be used to build high-efficiency thermoelectric modules. Recently, topological insulating properties have been discovered in Sb2Te3 powder. In addition, this has led to research on broadband nonlinear optical properties, including nonlinear absorption and refraction. This creates the opportunity to use it as a saturable absorber for Q-switched and gated-mode fiber lasers, for nonlinear beamforming and to achieve a super-resolution effect in nano-optics. Another crucial advantage is its broadband function, which allows it to be used in devices that operate in different spectral ranges in visible and infrared light.
