    Selenium is a chemical element from the group of chalcohols. Selenium, metallic and non-metallic modifications may exist. Grey metallic selenium is considered the most stable modification. It has semi-metallic properties. The red selenium is non-metallic and passes above 80°C into the grey metallic selenium. Third modification is black selenium. This converts above 80°C to grey metallic modification. In addition, selenium metal has six naturally occurring isotopes. Five of them are stable.

    Selenium has a great economic meaning and is essential for all forms of life. In medicine, selenium based preparations are used to treat skin diseases. To combat dandruff, selenium is used as 1% selenium sulfide SeS2 in shampoos. In the glass industry, selenium metal comes to the production of selenium ruby glass, which is used in signal and traffic light systems. Selenium also enjoys demand in the semiconductor industry.

    The main uses of selenium are:

    • Glass making (selenium ruby glass);
    • Medicine (treatment of skin diseases);
    • Semiconductor manufacturing;
