Application

1.It can be used as a filler for washing powder and soap.

2. It is also a raw material for the manufacture of optical glass, enamel and enamel. It can also be used to make artificial gems and fluxes. When borax melts, it becomes a colorless glassy substance and is used to manufacture special optical glass.
3. In analytical chemistry, borax beads can be used to identify metal ions.
4. The borax aqueous solution is alkaline and can be used as a soap and detergent powder filler.
5. Medically used as a preservative. Chinese medicine is used as a heat-clearing and antidote.
6. In the chemical industry is the raw material for the manufacture of a series of boron compounds.
7. Borax solution is used as a plant fertilizer.
