Boracic Acid
CAS: *********3
Specification: Purity *9% min
Molecular Formula: H3BO3
Molecular Weight: *1.*3
CAS No.: *********3
Property: White powder of scaled crystal, feeling greasy, odorless
and tasteless, soluble in water, alcohol, glycerol ether and
volatile oil, the water solution indicating weak acidity, when
heating to *****0 degree, hydro-extracting gently to change into
meta-boric acid; ******0. C, as pyro-boric acid: **0 degree, as
boric anhydride(B2O3).
Usage:
1. This product is widely applied in glass manufactured industry,
it is possible to improve the thermostabilization, transparency and
strength of the glass products.
2. It can improve fastness of the ceramics.
3. It may be used in medical industry.
4. It may be used in smelting, metal welding, leather and dye
etc.
5. It can be used as antiseptics, such as preventing the wood
septic.
6. It can be used as a boric microelement manure and a insecticide
too.
7. It can be as various boride widely applied in national defense
and scientific research departments.
Boric acid, also called boracic acid or orthoboric acid or acidum boricum, is a weak acid often used as an antiseptic, insecticide, flame retardant, in nuclear power plants to control the fission rate of uranium, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a white powder and dissolves in water.It has high quality and competitive price.
