High Purity Selenium 99.999% 99.9999% 5n 6n Selenium Metal Price Selenium Powder

Selenium is used in industries such as electronics, glass, metallurgy, chemicals, healthcare, agriculture, etc., with greater selenium consumption in the glass manufacturing, electronics, chemicals, and metallurgy industries, and less in other industries. With the emergence of substitutes for selenium in the electronics and battery industries, selenium consumption in this area will decline, while selenium in the glass manufacturing industry has not been a better alternative, so demand will continue to rise.
Selenium and its compounds are often used as catalysts, vulcanising agents and antioxidants. Selenium as a catalyst has the advantages of mild reaction conditions, low cost, low environmental pollution, and convenient post-treatment, such as mono selenium is the catalyst in the preparation of mono sulphur in the sulphite reaction. Selenium is often used as a vulcanising agent in rubber production to enhance the abrasion resistance of rubber.
Selenium has photosensitive and semiconductor properties, often used in the electronics industry to manufacture photocells, photoreceptors, laser devices, infrared controllers, phototubes, photoresistors, optical instruments, photometers, rectifiers and so on. The application of selenium in the electronic industry accounts for about 30% of the total demand. High purity selenium (99.99%) and selenium alloys are the main light absorbing media in photocopiers and are used in the photoreceptors of plain paper photocopiers and laser printers. An important feature of grey selenium is that it has typical semiconductor properties and can be used for radio wave detection and rectification. Selenium rectifiers are characterised by load resistance, high temperature resistance and good electrical stability.
