BORAX Anhydrous
Borax supplier and stockist in India, Middle East, Oman.
Application
Borax major utilization : Glass and porcelain industries are the major consumers of borax and boric acid.
It is an essential component of heat-resisting borosilicate glass, glass fibres and industrial & optical glass. In glass, enamels and ceramics, it controls thermal expansion, improves durability, assists melting processes and adds to inorganic colours and decorations.
Borax is used in medicine (boric powder), leather processing, adhesive, corrosion inhibition, ferrous wire manufacture, flame-proofing and timber preservation.
Borax is used as a flux in brazing, welding, soldering and in the manufacture of artificial gems like, cubic boron nitride, (commercially called Borazon) which equals diamond in hardness and boron carbide, titanium boride and tungsten boride which are next to diamond in hardness.
