Description

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. It is used to prepare buffers, which is used in gel electrophoresis of DNA. It acts as a source of borate, micronutrient fertilizer, preservative in taxidermy, additive in ceramic slips and glazes. It is also used as a precursor for sodium perborate monohydrate and boric acid. It finds application as fluoride detoxification, neutron absorber in nuclear reactors and to make indelible ink for dip pens.
