Zirconium Selenide 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.

Zirconium is a Block D, Group 4, Period 5 element. The electronic configuration is [Kr] 4d2 5s2. In its elemental form zirconium's CAS number is 7440-67-7. The zirconium atom has a radius of 159.pm and it's Van der Waals radius is 200.pm. Zirconium is primarily used in it's oxide or zirconia form. Zirconium dioxide has a high melting point (2,700° C) and a low thermal conductivity. Its polymorphism, however, restricts its widespread use in ceramic industry. During a heating process, zirconia will undergo a phase transformation process. The change in volume associated with this transformation makes the usage of pure zirconia in many applications impossible.

Selenium is a Block P, Group 16, Period 4 element. The electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. These properties make selenium useful in the production of photocells and exposure meters for photographic use, as well as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications.

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
