High quality boric acid powder production by nitric acid method 99.6%min
► Description
Boric acid, white powder crystal or triclinic axial surface scaly luster crystal, have greasy feel,
no smell.Soluble in water, alcohol, glycerin, ethers and essential oils, the aqueous solution is weakly acidic.
It is widely used in glass (optical glass, acid-proof glass, heat-resistant glass, fiberglass for insulating
materials) industry, which can improve the heat-resistant and transparent performance of glass products,
improve the mechanical strength and shorten the melting time.
►Specification
Item | Specification |
| H3BO3 | ≥ 99.60% |
| NH3 | ≤0.60% |
| SO4 | ≤0.30% |
| CL | ≤0.15% |
| Fe | ≤0.06% |
| Water insoluble | ≤0.06% |
►Preparation
Boric acid may be prepared by reacting borax (sodium tetraborate
decahydrate) with a mineral acid, such as hydrochloric acid:
Na2B4O7·10H2O + 2 HCl → 4 B(OH)3 [or H3BO3] + 2 NaCl + 5 H2O
It is also formed as a by product of hydrolysis of boron trihalides and
diborane
B2H6 + 6 H2O → 2 B(OH)3 + 6 H2
BX3 + 3 H2O → B(OH)3 + 3 HX (X = Cl, Br, I)
►Application
1.Boric acid is widely applied in glass manufactured industry, it is used to improve the thermostabilization,
transparency and strength of the glass products.
2.Boric acid can improve fastness of the ceramics.
3. Boric acid can be used in medical industry.
4.Boric acid can be used in smelting, metal welding, leather and dye etc.
5.Boric acid can be used as antiseptics, such as preventing the wood septic.
6.Boric acid can be used as a boric microelement manure and a insecticide too.
7.Boric acid can be as various boride widely applied in national defense and scientific research departments.
►Packing details
Packing :25/50KG plastic pp bag,or customized.
