Sodium selenite (Na₂SeO₃) is a crucial inorganic compound that serves as a primary source of selenium for a multitude of applications across various industries. Its unique chemical properties make it indispensable in sectors ranging from animal nutrition and food fortification to advanced materials manufacturing and agricultural science. For procurement managers, R&D scientists, and product formulators, understanding the capabilities and sourcing of high-quality sodium selenite is vital.

Key Properties and Characteristics

Sodium selenite typically appears as a white to light beige crystalline powder. It is highly soluble in water, with a notable solubility of 950 g/L at 20°C, a characteristic that facilitates its incorporation into aqueous solutions and formulations. While stable under normal conditions, it is important to store it appropriately, away from incompatible substances and in a cool, dry environment.

With a molecular formula of Na₂SeO₃ and a molecular weight of 172.93800, its precise chemical composition ensures predictable performance in its applications. The selenium content in high-purity sodium selenite typically ranges from ≥44.7% to ≥45.5%, making it a concentrated and efficient source of this essential element.

Diverse Applications Across Industries

The versatility of sodium selenite is one of its most significant advantages. Its key applications include:

  • Nutrition Enhancer: Widely used in the medicine and feed industries to provide essential selenium, crucial for antioxidant defense, immune function, and reproductive health in both humans and animals.
  • Glass and Ceramics: It acts as a decolorizing agent to remove unwanted tints from glass and is used to create vibrant red and pink colors in glass and glazes.
  • Agriculture: Applied to soils to enrich them with selenium, thereby increasing the nutritional content of crops and improving overall plant health.
  • Scientific Research: Employed as a reagent in laboratories for studies related to selenium's biological roles and therapeutic potentials.
