Selenium is a good physical decolorizer, which is often used in glass industry.
# 99.999% selenium granule Metallurgical industry.
Selenium can improve the machinability of steel, so it is often used in metallurgical industry. Adding 0.3% - 0.5% selenium to cast iron, stainless steel and copper alloy can improve their mechanical properties, make their structure more compact, can be cut at high speed, and the surface of machined parts is more smooth. The alloy composed of selenium and other elements is often used to make low-voltage rectifiers, photocells and thermoelectric materials.

Selenium and its compounds are often used as catalysts, sulfurizers and antioxidants. Using selenium as catalyst has the advantages of mild reaction conditions, low cost, small environmental pollution and convenient post-treatment. For example, selenium is the catalyst in the process of sulfite reaction to prepare sulfur. Selenium is often used as curing agent to enhance the wear resistance of rubber.

Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-p protein in animals and human body, which can improve human immunity, and has a good prevention and treatment effect on cancer, stomach disease, cardio cerebrovascular disease, prostate disease, vision disease, etc. Therefore, selenium is widely used in the medical field to treat and alleviate various diseases caused by selenium deficiency. As selenium is a necessary microelement for human body and has an important impact on human health, the medical and health care industry has started to develop various selenium supplement products, such as malt selenium.

In agricultural production, selenium can be added to fertilizer to improve the state of soil selenium deficiency and promote plant growth. Selenium is also used in cosmetics. Some cosmetics containing selenium have anti-aging effect. In addition, adding selenium to the plating solution can improve the appearance of the plated parts, so it is also applied to the electroplating industry.
