Sodium tetraborate is used as a co-catalyst for (2,2,6,6-tetramethylpiperidin-1-yl)oxyl and sodium hypochlorite oxidation of alcohols in greener and non-chlorinated solvents. it acts as a reagent for the decomposition of oxides and silicates by fusion. Anhydrous borax is also termed as sodium tetra-borate, dehydrated borax, or calcined borax is a raw, granular, hard, glassy material for the preparation of boron compounds like metallurgy, glass, enamels and coatings, fiberglass, and cleaning products. it is made by fusing or burning hydrated borax.
Anhydrous borax is white solid crystalline product used in gold smelting as a flux. the advantages of using borax in gold smelting are: facilitates separation of the gold from gangue at lower temperatures; borax forms a structural network with rock silicates that captures metal ions which normally associate with oxides eg.
