Applications of Sodium Selenite 

Food Sector

• Food-grade Sodium Selenite can be used in the production of dietary supplements (multivitamin and mineral tablets) or fortified foods (selenium-fortified salt, biscuits, oatmeal, etc.) to provide the human body with an appropriate amount of selenium and correct and prevent selenium deficiency.
• Sodium Selenite additives in pet food (for cats, dogs, etc.) are generally higher than those in ordinary feed-grade products and tend to be food-grade in high-end products. Sodium selenite is a safe, economical, and effective source of selenium to meet pets’ selenium requirements.
• Feed-grade Sodium Selenite can be added in trace amounts to animal feed as a selenium supplement to prevent white muscle disease and reproductive disorders caused by selenium deficiency in poultry and livestock; or to enhance the immunity and stress resistance of fish and crustaceans.
• Sodium Selenite can increase the selenium content of crops through foliar fertilizers and soil conditioners, expanding the range of selenium sources in food, and facilitating the supplementation of selenium in humans and animals such as cattle and sheep.

Medical Field

• Pharmaceutical-grade Sodium Selenite can be used to produce sodium selenite tablets or solutions for the treatment of selenium deficiency with a confirmed diagnosis.
• The selenium element in pharmaceutical-grade Sodium Selenite is used in medical research for applications such as anti-tumor treatment, anti-inflammatory effects, and regulating thyroid function.

Industrial Sector

• Industrial-grade Sodium Selenite is a key decolorizing and coloring agent in the glass industry.By utilizing the principle of complementary colors, the glass is rendered colorless, enabling the production of high-quality optical glass, crystal glass, and other types of glass;Through mixing, “selenium red” glass can be produced for use in traffic lights, art glass, and other applications.
• Electronic-grade Sodium Selenite is used in the electronics industry as a raw material and dopant for functional materials.Sodium selenite can be used to prepare various selenide raw materials for optoelectronic materials or as a selenium source in the production of high-purity semiconductor materials.
• In the chemical industry, Sodium Selenite is used as a catalyst (such as in the oxidation of aldehydes and specific cyclization reactions in organic synthesis), an analytical reagent (such as an oxidation-reduction titrant or chromogenic reagent), and a synthetic intermediate (for organic selenium compounds or selenium powder, etc.).
