High quality 99.9%min Selenium Granule

Selenium granules are a common inorganic nanomaterial with many excellent properties and application prospects. Selenium granules are a solid with a gray metallic luster. Selenium particles are brittle, toxic, and conductive, and their conductivity changes sharply with the intensity of light. Selenium particles can be oxidized by nitric acid and dissolved in concentrated alkaline solution, and will not be oxidized at room temperature.

Application

1. Selenium has good photovoltaic and photoconductive properties, and it is used extensively in electronics, such as photocells, light meters and solar cells.

2. The second largest use of selenium is in the glass industry: selenium is used to remove colour from glass, to give a red colour to glasses and enamels.

3. The third min use, taking about 15% is sodium selenite for animal feeds and food supplements.

4. Selenium can also find applications in photocopying, in the toning of photographs. Its artistic use is to intensify and extend the tonal range of black and white photographic images.

5. Other uses of selenium are in metal alloys such as the lead plates used in storage batteries and in rectifiers to convert AC current in DC current.

6. Selenium is used to improve the abrasion resistance in vulcanized rubbers. Some selenium compounds are added to anti-dandruff shampoos.
