Boric anhydride, 98.50%+

Product Introduction

Boric anhydride is a boron-based inorganic oxide with a molecular weight of 69.62 g/mol. It is commonly supplied as a white powder or crystalline/glassy solid and has a melting point of approximately 450 °C. B₂O₃ is an important glass-forming oxide and can interact with other metal oxides to modify glass structure, thermal behavior, chemical durability, and optical properties.

Its combination of glass-forming ability, fluxing behavior, and boron-containing composition makes Boric anhydride useful in glass and ceramic processing, functional inorganic materials, semiconductor-related research, and other advanced-material applications.

Mechanism / Principle

Boric anhydride primarily functions through its ability to participate in inorganic oxide networks and modify the structure and properties of glass and ceramic systems.

• Glass network formation – B₂O₃ can act as a glass-forming oxide and participate in borate-based and mixed-oxide glass networks.
• Fluxing action – It can facilitate melting and processing of oxide mixtures by modifying the melting behavior of inorganic compositions.
• Network modification – Interaction with other metal oxides can alter glass structure, thermal properties, chemical stability, and optical characteristics.
• Boron source – B₂O₃ provides boron for the preparation of borides, boron-containing ceramics, and other inorganic boron compounds.
• Materials-property control – Its incorporation into glass and ceramic formulations can be used to tune material properties for specific research objectives.

Storage & Handling

Boric anhydride is hygroscopic and can react with moisture to form boric acid. It should therefore be stored in a tightly closed container in a cool, dry environment and protected from unnecessary exposure to atmospheric moisture.

Handle the material using appropriate laboratory chemical-safety procedures and consult the applicable SDS before use. Avoid unnecessary contact with moisture and incompatible chemicals.
