99.9% Bismuth (Bi) Metal Powder CAS 7440-69-9

semiconductor

Bismuth-containing semiconductor materials for thermoelectric chillers are widely used in the electronics industry, and Bi-Te-Se thermoelectric chillers are more widely used. The use of multiple stages can reduce the temperature to below 200K, which is useful in the military, aerospace industry, scientific research experiments, can maintain or reduce the temperature of solid-state circuit laser sources, infrared detectors and charge-coupled devices, It is used in the automatic scanning array system of astronomical telescope camera, navigation laser, light wave transmitter, medical laser instrument, temperature observer infrared tracking missile, high resolution charge-coupled device camera, rifle thermal sight, black body reference object, etc. Container refrigeration can be used in small pressurized air refrigeration systems, mandryer, NASA life science environment cabin, electronic shielding room, chip thermal characteristics identification instrument, etc. It can also be used in high speed integrated circuits, parametric amplifiers, ion avalanche photodiodes, photoconductive video tubes, etc. BisbTe3 can be used as a thermoelectric component for solar cells :BiTe2 is used to manufacture low-temperature thermoelectric power supplies; BiAgS2 is used to manufacture semiconductor devices, such as Bi203 thin film materials composed of non-stoichiometric oxides can be used as conductive coatings.

Artificial bismuth sulfide (Bi2S3) is mainly used as a high-temperature lubricant and semiconductor raw material to manufacture photoresistance in photoelectric automatic equipment to increase the sensitivity of the spectrum in the visible spectral region.
