Properties:
White powder crystal, specific weight 1.69-1.72, hardness 2-2.5, soluble in water, insoluble in alcohol, the solution indicating weak alkalinity, heating to 350-400��/span>, losing the crystal water and changing into waterless borax, it features sterilizing, decontaminating, melting-aid and pyre-adhesive property etc
Applications:
1) It may be made of optical glass, anti-heat and antiseptic glasses in glass manufactured industry.
2) It may be used as a cover coat which may be coated on the surfaces of metals to strong and durable for ceramics.
3) As a cover coat, that can have good effect for ceramics.
4) it can be used as an addition matter at the electrolytic bath and welding fluxes of color metals for color metal industry.
5) It can be made of specific alloys in smelting industry.
6) It can be used as a micro-quantity element manure and sterilizing agent for agriculture.
7) Borax is also a main material for boride and high energy doron hydride combust.
