Iridium Telluride is a crystal grown product generally immediately available in most volumes. technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Iridium Telluride (IrTe) is also available as Quantum Dots. IrTe Quantum Dots have the widest wavelength range reaching sizes as small as less then 500 nm; within the range sufficient to emit light in the blue-white range. Iridium Telluride Quantum Dots are charged aqueous soluble nano crystals with narrow emission spectra from 490 nm to 740 nm. Iridium Telluride (IrTe) is also used in solar energy and advanced optical applications.

Iridium is a Block D, Group 9, Period 6 element. The electronic configuration is [Xe] 4f14 5d7 6s2. In its elemental form iridium's CAS number is 7439-88-5. The iridium atom has a radius of 135.7.pm and it's Van der Waals radius is 200.pm. Iridium is a member of the platinum group of metals. It is the most corrosion resistant metal known. It will not react with any acid and can only be attacked by certain molten salts, such as molten sodium chloride. It is alloyed with platinum to produce highly corrosive resistant electrical contacts for spark plugs.

Tellurium is a Block P, Group 16, Period 5 element. The electronic configuration is [Kr] 4d10 5s2 5p4. In its elemental form tellurium's CAS number is 13494-80-9. The tellurium atom has a radius of 143.2.pm and it's Van der Waals radius is 206.pm. Tellurium is a p-type semiconductor, and shows greater conductivity in certain directions, depending on alignment of the atoms. It is grown in crystalline form with other elements such as indium telluride. Its conductivity increases slightly with exposure to light which makes many tellurides candidates for solar energy applications. . Tellurium improves the machinability of copper and stainless steel, and its addition to lead decreases the corrosive action of sulfuric acid on lead and improves its strength and hardness. Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control. Tellurium is used in ceramics.

American Elements semi conducting materials are crystal structures produced from ultra high purity starting materials synthesized by our high purity production facility which includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors supported by our analytical laboratory containing X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis. See a discussion of American Elements Ultra High Purity and Analytical capabilities. See Crystal Growth for processes used to fabricate semiconductor materials, which include:

  • Crystal "pulling" by the Czochaiski method for production of semiconductor materials
  • Flux growth and gradient freeze
  • Directional solidification of fluorites using both the Bridgman-Stockbarger and float zoning techniques
