eiddo a Defnydd:

Selenium dioxide (SeO₂), CAS 7446-8-4, is a colorless to white solid compound with strong oxidizing properties.

1. High-efficiency oxidant for organic synthesis

As a strong oxidant, selenium dioxide is used to oxidize compounds such as aromatic hydrocarbons and alcohols, and as a catalyst in the synthesis of selenium compounds.

2. Photoelectric and semiconductor materials

Selenium dioxide is a key raw material for photoelectric materials such as cadmium selenide, and is used in the production of solar cells and photodetectors.

3. High-performance glass manufacturing

Used as an additive for optical glass to improve refractive index and transparency, suitable for optical and special glass production.

4. Electrolytic metal and chemical applications

As a core intermediate in the manufacture of electrolytic manganese and selenide, it helps the development of the chemical industry.
