Description

Sodium Selenate Decahydrate is a high-purity inorganic salt that serves as a vital source of bioavailable selenium. This compound is essential for applications requiring a consistent and reliable supply of selenium in a soluble, stable form. It is a critical raw material for manufacturers in the animal nutrition, pharmaceutical, and specialty chemical industries seeking to meet precise formulation requirements.

Application

• Animal Feed Additive: A key source of selenium in vitamin-mineral premixes for livestock and poultry to prevent deficiency disorders and support immune function.
• Dietary Supplements: Used in the formulation of human nutritional supplements and functional foods to provide essential trace mineral selenium.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) where selenium is a required component.
• Glass Manufacturing: Acts as a decolorizing agent to neutralize the green tint caused by iron impurities in glass batches.
• Agricultural Solutions: Utilized in foliar sprays and fertilizer blends to correct selenium deficiencies in soils and crops.
• Research & Development: Serves as a standard and reagent in analytical chemistry, biochemistry, and life science research laboratories.
• Electroplating & Metallurgy: Used in specific electroplating baths and as an additive in metal alloy production.
