Purity: 99.99%

Cadmium Telluride powder CdTe Powder:
Cadmium telluride's chemical formula is CdTe. The molecular weight of the drug is 240.00. Its melting point is 1041. When the temperature rises, it will melt. It's insoluble in acids and water but it can be reduced by reacting to nitric. If it gets wet, it can be easily oxidized using air.
Cadmium telluride, also known as CdTe (cadmium telluride), is a stable crystal compound that has been made from tellurium and cadmium. It's primarily used in semiconductor materials and as an infrared light window in photovoltaic cells containing cadmium. This is typically sandwiched together with cadmium sulfuride in order to create a pn junction solar PV cell. CdTe PV cells generally use an N-i-p configuration.
Bulk CdTe, also known as bulk CdTe, is transparent in the Infrared. This transparency can range from very close to its bandgap energie (1.5 EV at 300K, corresponds to an wavelength of approximately 830nm infrared) to wavelengths higher than 20 um. CdTe fluoresces in the 790 nm range. Fluorescence peaks are seen in ultraviolet light when CdTe is reduced to about a nanometer or less.
CdTe can not be dissolved in water. CdTe melts at 1041°C, and then evaporates at 1050°C. CdTe has a zero vapor pressure at ambient temperatures. CdTe's high melting point, insolubility and stability make it more stable that its Cd parent compounds (cadmium, tellurium, and many other Cd compounds).

Cadmium Telluride Cadmium Telluride Powder Performance:

Cadmium Telluride is a crystal made of cadmium, tellurium. For a photovoltaic cell with p-n junction, the compound is sandwiched together with calcium sulfuride. It has a low solubility and can be easily etched using many acids, such as hydrobromic acid and hydrochloric. You can purchase it in powder form or as crystals. Nanocrystals can be also made from this substance.

How does Cadmium Telluride Powder Powder CdTe Pulsed get made?
Cadmium tellurum, melted in a hydrogen stream or cadmium tellurite. Tellurite can also be heat and reduced by a hydrogen stream. This reaction can be done with sodium telluride or a solution of cadmium acid acid acidified by Acetic acid. After precipitation, it turns brownish red and becomes almost black upon drying. To form one crystal of cadmium-telluride, you can react on cadmiumvapor and hydrogen telluride. Cadmium telluride, which is made from high-purity tellurium (and cadmium) as its raw material, can be synthesized by deoxidation. Then it's grown to a single or multiple crystals or polycrystalline using either the vertical crystallization process or the vertical zone melting process.

Cadmium Telluride powder CdTe Powder Application:
Most commonly, CdTe can be found in photosensitive crystals and thermal cells. You can use it in additives for industrial purposes such as alloys, chemical raw material, and cast iron.
To make thin-film solar cell, you can use CdTe.
You can mix CdTe with mercury to create an universal infrared detection material (HgCdTe).
CdTe, which is an alloyed CdTe with some zinc, can provide excellent solid-state X/ray and gamma ray detectors (CdZnTe).
CdTe has excellent performance at all temperatures and is commonly used in infrared lenses and optical windows.
CdTe also finds its way into electro-optic modulators. CdTe is one of the II/VI compound crystals with the highest electro-optic coefficients in linear electro-optic effects (r41 =r52 =r63 = 6.8x10-12m/V).
A CdTe-doped with chlorine can be used as radiation detector to detect X, gamma, beta, and alpha particles.
CdTe operates at room temperature so it is possible to make a compact detector for different applications in nuclear spectrum.
CdTe is a high-performance detector for high-performance gamma and X-rays. This is due to the high atomic number and high charge collection. It also has excellent spectral clarity.
