Cadmium Telluride Puffer CdTe powder:
Cadmium telluride can be described chemically as CdTe. It has a molecular weight 240.00 and certain liver- and kidney toxicities. It has a melting temperature of 1041. At higher temperatures, it can melt. It is insoluble with acid and water. However, it can be made to dissolve in nitric or other acidic solutions. It can be easily reduced by the presence of oxygen when it’s wet.
Cadmium telluride is a stable crystalline substance made of tellurium (CdTe). It is mostly used to make semiconductors and for infrared windows in cadmium photovoltaic systems. This is typically sandwiched together with cadmium-sulfide in order to form a solar photovoltaic p–n junction cell. CdTe PV solar cells typically use an in-i-p configuration.
Bulk CdTe shines transparently in the near infrared. The bandgap energy of 1.5 eV at 300K corresponds to an wavelength of 830 nm infrared. CdTe fluoresces in 790 nm. CdTe quantum dots are formed when CdTe crystals become a fraction of the original size. The fluorescencepeaks then shift towards ultraviolet light.
CdTe does not dissolve in water. CdTe, which has a 1041°C melting point and is evaporable at temperatures of 1050°C, has zero vapor pressure. CdTe due to its high melt point and insolubility makes it much more stable that its parent compounds, cadmium or telluride.
Cadmium Telluride Cadmium Telluride CdTe powder Product performance
Cadmium informuride is an crystalline compound made from cadmium or tellurium. The pn junction photovoltaic-solar cell is formed by it being sandwiched in calcium sulfide. It is very insoluble in water. It can also be etched by hydrobromic and chloric acids. It’s available commercially as powder or crystals. You can also make nanocrystals out of it.

How is Cadmium Telluride Pulver CdTe Powder manufactured?
Cadmium and tellurium mix are sublimated, melt and reduced in a hydrocarbon stream. Also, sodium telluride with a cadmium solution acidified in acetic can act to react. It turns brownish when precipitated and nearly black once dried. Cadmium telluride can be formed by reacting with hydrogen and cadmium vapor to create a single crystal. Cadmium telluride synthesized from high-purity Tellurium or cadmium is obtained by using high purity tellurium or cadmium as its raw materials. This telluride then grows into one or more crystals or polycrystalline via either the vertical crystallization procedure or the vertical area melting method.
Cadmium Telluride – Powder CdTe –
You can use CdTe in your solar cells, thermoelectric convert elements, refrigerator components, thermal and photosensitive crystals as well as in nuclear radiation detection, infrared detectors, and for other purposes. This industrial additive can also include CdTe in alloys, raw materials for chemical and mechanical reactions, as well as cast iron, rubber and Glass.
The CdTe material is used in the fabrication of thin-film solar batteries.
Infrared detector materials can be made by combining CdTe and mercury.
CdTe could be an excellent solid state X/ray/gamma-ray detector (CdZnTe), which uses CdTe that has been mixed with small amounts zinc.
CdTe is used for infrared optical materials such as optical lenses or windows. The material has proven its ability to perform well at high temperatures.
CdTe is used also in the manufacture of electro-optic modulators. CdTe has the greatest electro-optic value among all II-VI compound compounds. (r41 = R52 = Rh63 = 6.810-12 M / V).
For radiation detectors such as X-rays or gamma rays as well beta and alpha particle detection, CdTe that has been doped with chlor is employed.
CdTe will operate at ambient temperature. This makes it possible to build a small detector that can serve various nuclear spectroscopy applications.
CdTe has a remarkable record in realizing high performance gamma/x-ray detectors.
