概要

Selenium powder is a fine, powdery substance made up of small particles of the element selenium, often produced by the reduction of selenium oxide. Selenium powder is grey or silvered-colored and may have a metallic sheen. This product is passed through a 100-mesh sieve, indicating that the particles are small and have a diameter of around 150 micrometers or less. In addition, this product is highly pure and only has a very small concentration of impurities, making it suitable for research applications, chemical testing, and the production of electronic components.
