| Form: Granular |
Anhydrous borax, chemically known as sodium tetraborate anhydrous (Na2B4O7), is a white, crystalline powder that occurs naturally in evaporite deposits produced by the repeated evaporation of seasonal lakes. This form of borax has had its water of crystallization removed, distinguishing it from the more commonly encountered borax decahydrate (Na2B4O7·10H2O). Anhydrous borax is more concentrated than its hydrated counterpart, making it more potent in various applications.
- Glass and Ceramics Industry:
- Glass Manufacturing: Anhydrous borax is used to reduce the melting temperature of glass and to improve its durability, clarity, and resistance to chemical and thermal shock.
- Ceramics: It acts as a flux in ceramics production, helping to control the temperature at which the glaze sets on the ceramic body and improving the strength and aesthetic qualities of ceramic products.
- Laundry and Cleaning Products:
- Detergents and Cleaners: Borax is a component in various laundry detergents, boosters, and household cleaners, where it softens water, enhances cleaning efficacy, and acts as a mild antiseptic.
- Agriculture:
- Fertilizers: It is used as a micronutrient fertilizer in agriculture to supply boron, an essential nutrient for plant growth.
- Pest Control: Borax is employed in some pest control products for its ability to act as an insecticide, particularly against ants and cockroaches.
- Metallurgy:
- Metallurgical Flux: In metallurgy, anhydrous borax is used as a flux to prevent oxidation during the smelting of metals. It helps to remove impurities and assists in the refining of metals like gold, silver, and copper.
- Adhesives and Glues:
- Manufacturing of Adhesives: It is used in the production of adhesives, including those for wood, paper, and textiles, to improve adhesion and flexibility.
- Pharmaceuticals and Cosmetics:
- Preservative and pH Buffer: In pharmaceuticals, anhydrous borax serves as a preservative and a buffer to maintain the pH of solutions. In cosmetics, it's used in various products for its antiseptic properties and to emulsify fats and oils.
- Nuclear Industry:
- Neutron Absorber: Borax can be used as a neutron absorber in nuclear reactors to control the nuclear fission process.
- Fire Retardants:
- Flame Retardant: It is used in the formulation of fire retardants for textiles, woods, and other materials, helping to reduce flammability and spread of fire.
- Chemical Industry:
- Intermediate in Chemical Synthesis: Anhydrous borax serves as a reactant or a catalyst in the synthesis of various chemical compounds, including those in organic synthesis and polymer production.
These applications illustrate the versatility and importance of anhydrous borax in numerous fields, from industrial manufacturing processes to everyday household products. Its role in enhancing the performance, safety, and effectiveness of products makes it a valuable resource in multiple sectors.
