Applicazioni

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.

Note

Hygroscopic. Incompatible with potassium, acid anhydrides and powdered metals.
