Product Description
Boron oxide is a colorless glassy solid that is used as an insecticide fluxing agent and bonding agent. It is also known as boric oxide or boria. Boron oxide (B₂O₃), also known as boric oxide or diboron trioxide, is a colorless, glassy solid formed by the dehydration of boric acid. It is a key compound used in various industries, including glass, ceramics, and electronics, and is known for its high-temperature resistance and ability to act as a fluxing agent.
Application
APPLICATION::
Glass and Ceramics:
- Borosilicate Glass: Boron oxide is a key ingredient in borosilicate glass, known for its high thermal resistance and chemical durability, making it suitable for applications like laboratory glassware, cookware, and ovenware.
- Fluxing Agent: It acts as a flux in the production of glass and enamels, lowering the melting temperature and improving the flow of the molten materials.
- Glass Fibers: Boron oxide is used as an additive in glass fibers, including optical fibers.
- Ceramic Applications: It's used as a bonding agent in the hot isostatic pressing of boron nitride ceramics and as a flux for glazes and enamels.
Dose
Chemical Synthesis and Catalysis:
- Starting Material: Boron oxide serves as a starting material for the synthesis of other boron compounds, such as boron carbide.
- Acid Catalyst: It acts as an acid catalyst in organic synthesis and the preparation of boron halides, sodium borohydride, metallic borates, and borate esters.
- Chemical Intermediate: It's used as a chemical intermediate in the production of boron halides, esters, carbide, nitride, and metallic borides.
