1.Usage:
Boric acid is used extensively for the glass industry, in particular E-glass fibers, but also can not be substituted borax. In the enamel, ceramic industry, products used to enhance the gloss and fastness. Can be used for medicine and wood preservation. Fungicides can be done in agriculture, pesticides, and trace element fertilizers. Boric acid is produced diboride matrix material, and its metal welding, leather, precious stones, electronics, defense and scientific research departments have widely applied..
2. Appearance: White crystal powder or three oblique axial plane of the scaly and shiny crystal.

4. Properties:
Boric acid is actually oxidation boron hydrate (B2O3, 3H2O), for white powder crystallization or three inclined shaft side flake crystallization, have satiny gloss, no odor. Handle Proportion 1.435 (15 °C). Soluble in water, alcohol, glycerin, ethers and oils, aqueous show weakly acidic. The solubility of boric acid in water with temperature and increase, and can change with steam volatile, In the solubility inorganic acid than in water solubility of small. Heated to 70 to 100 °C gradually dehydration generating partial boric acid, 150 ~ 160 °C when coke boric acid, 300 °C generated boric acid anhydride (B2O3).
5. Description:Boric acid, also called boracic acid or orthoboric acid or acidum boricum, is a weak acid often used as an antiseptic, insecticide,flame retardant and a precursor of other chemical compounds. White powder of scaled crystal, feeling greasy, odorless and tasteless. Soluble in water,alcohol, glycerol ether and volatile oil.
6. Features: touched with the skin have satiny feeling, no smell, taste slightly acidic after bitter and sweet.
7.Storage: Seal save. Should be stored in a dry, clean inside storeroom, open air are not, should avoid to rain or moisture
8.Transportation: Should be installed in boxcars, the cabin or covered in a car transport, and shall not and wet items and non-ferrous ingredients piled up, transportation must be dry clean.
9. Stability: Boric acid is a stable crystals, usually preserved won't happen the chemical reaction. Temperature, humidity drastic change happens when heavy crystallization and agglomerate.
10. Package: PE bag lined with plastic woven bag, net weight 25 kg.
