English another name: Boric oxide, Boron oxide, Boric anhydride

CAS RN: 1303-86-2

1. Physical and chemical properties:

1.1 Molecular formula: B₂O₃

1.2 Molecular weight: 69.62

1.3 Melting point: 450℃

1.4 Boiling point:1860℃

1.5 Density: 1.085 g/mL (Amorphous)

1.6 Solubility: Dissolved in acid, ethanol, hot water, and slightly dissolved in cold water.

1.7 Properties: Colorless crystal powder. Be greasy in the surface. With strong hygroscopicity, it is easy to be hydrolysised to form boric acid. In high temperature, it can be reduced by alkali metal or magnesium to monocrystal boron. It can be completely mixed with the oxides of metal, copper, sliver, aluminum, tin, arsenic.

2. Technical indexes:

Item	1^st grade	2^nd grade
Boron oxide, %(m/m)	≥98.0	≥95.0
Appearance	White loose powder

3. Uses: It has been used as the fusion agent in decomposition of silicates, the dopant of semiconductor material, the additives of heatproof glassware and paint refractory. It has been used in production of alloy steel in metallurgical industry. In addition, it’s used as the catalyst of organic synthesis, the additive of lubricant used in high temperature, and can be also used to environmental protection.

4. Safety instructions: Toxic by ingestion, inhalation, eye and skin contact. Eye and skin contact can cause inflammation. The maximum allowable concentration of the working place is 15 mg/m³(OSHA). Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing.

5. Package: Woven bag with two-layer plastic bag, 25 kg net each.

6. Storage: Store at cool, dry and ventilate. Shelf life of 12 months, if expire, still used if up to standard through retest. Used in a dry place. With high humidity, it may crystallize and caking. Stay away from the variable environment to ensure complete packaging.

7. Transportation：Avoid rain, sunlight and crash. Don't mix with strong oxidizer.
