Boron Oxide (B₂O₃) is a chemical compound made of boron and oxygen. It is a white, amorphous or crystalline powder, depending on its form and the conditions under which it is prepared. Boron oxide is widely used in industrial applications, such as the production of borosilicate glass, ceramics, and as a flux in metallurgy. It also plays a role in electronics, optics, and chemical processing.
Chemical formula：B₂O₃
Molar mass：69.6182 g/mol
Appearance: White, amorphous powder, though it can crystallize under certain conditions. The crystalline form has a glassy or translucent appearance.
Density: Approximately 2.46 g/cm³ for the solid form.
Melting Point: Around 450°C, though it can vary depending on its form (amorphous boron oxide melts at a lower temperature).
Boiling Point: 3000°C (for the vapor phase).
Solubility: Boron oxide is soluble in water, forming boric acid (H₃BO₃) in a reaction with water.
Reactivity: Boron oxide is a powerful dehydrating agent and reacts with water to form boric acid. It also reacts with bases and alkaline oxides.
Purity: High-purity grades are available, typically around 99% or higher for specialized applications.
Glass Production: Boron oxide is a key ingredient in the production of borosilicate glass, which is known for its low thermal expansion and high resistance to thermal shock. This makes borosilicate glass ideal for laboratory glassware, cookware, and certain optical components.
Ceramics: Used in the production of certain ceramic materials, especially in high-temperature applications, where its high melting point and chemical stability are beneficial.
Flux in Metallurgy: B₂O₃ is often used as a flux in the production of metals and alloys, particularly in the production of steel and non-ferrous metals, to help remove impurities and lower the melting point of metals.
Electronics: In the electronics industry, boron oxide is used in semiconductor fabrication and for the manufacture of certain types of capacitors and resistors.
Optical Materials: Boron oxide is used in the manufacture of optical materials, including certain types of lenses, optical fibers, and coatings, due to its refractive properties and ability to form stable, high-performance materials.
Flame Retardants: Boron oxide is used in the production of flame-retardant materials, as it helps to inhibit the combustion of certain materials.
Chemical Synthesis: B₂O₃ can act as a catalyst or reagent in various chemical reactions, especially in organic chemistry, to form boron-containing compounds.
Protective Equipment: Always wear gloves, goggles, and a dust mask when handling boron oxide to prevent inhalation or skin contact.
Storage: Store in a dry, airtight container away from moisture and water to prevent the formation of boric acid. Ensure it is stored in a cool, dry location.
First Aid: In case of inhalation, move to fresh air. In case of skin contact, wash thoroughly with soap and water. If ingestion occurs, seek medical attention immediately.
