Oxobarium

Oxobarium is an inorganic compound with the chemical formula BaO, also known as barium oxide. This white crystalline solid has a molecular weight of 153.33 g/mol and serves as an important industrial chemical. It is formed by the oxidation of barium metal or thermal decomposition of barium compounds like barium carbonate or barium nitrate at high temperatures.

Oxobarium is a white crystalline solid at room temperature with a cubic crystal structure. It has a high melting point of approximately 1,920°C and exhibits basic properties, reacting vigorously with water to form barium hydroxide. The compound is hygroscopic, meaning it readily absorbs moisture from air, and shows limited solubility in polar solvents.

Oxobarium is primarily used in the glass industry as a flux and to increase the refractive index of optical glass. It serves as a raw material for producing other barium compounds and finds applications in ceramics manufacturing. The compound is also utilized in the production of cathode ray tubes, specialized optical equipment, and as a drying agent in various industrial processes.

Oxobarium should be handled with appropriate personal protective equipment including safety goggles, protective gloves, and respiratory protection to prevent inhalation of dust particles. Work in well-ventilated areas and avoid generating dust clouds. Keep containers tightly closed when not in use and ensure proper hygiene practices including thorough handwashing after handling to prevent accidental ingestion.

Oxobarium must be stored in dry, well-ventilated areas away from moisture due to its hygroscopic nature. Keep containers tightly sealed and protected from water contact, as the compound reacts with moisture to form barium hydroxide. Store away from acids and incompatible materials, maintaining ambient temperature conditions in a secure area accessible only to trained personnel.

In case of skin contact with oxobarium, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush eyes with clean water for 15 minutes while holding eyelids open. In case of inhalation, move to fresh air immediately. Seek medical attention if irritation persists or if ingestion occurs.

Oxobarium disposal must comply with local and national waste regulations as it contains barium, which can be environmentally hazardous. Contact licensed waste disposal companies specialized in inorganic chemical waste. Do not dispose of in regular trash or pour down drains. Small quantities may require neutralization before disposal, but always consult local environmental authorities for specific disposal requirements.

Oxobarium is classified under ADR class 6.1 (toxic substances), packing group III for transport purposes. This classification requires appropriate hazardous goods packaging, labeling, and documentation during transport. Vehicles must carry proper placards and drivers need hazardous materials training certification. Ensure packages are properly sealed and protected from moisture during transit to prevent chemical reactions.

Oxobarium falls under REACH regulation requirements in Europe, requiring registration for commercial use above certain tonnage thresholds. While not classified as a SVHC (Substance of Very High Concern), it must comply with CLP regulation for classification, labeling, and packaging. Users should maintain safety data sheets and ensure proper risk assessments are conducted for workplace exposure scenarios.

Oxobarium is available through OYSI, a European distributor of technical chemicals serving industrial customers across Europe. OYSI provides quality oxobarium with proper documentation including certificates of analysis and safety data sheets. As a specialized chemical distributor, OYSI ensures compliance with European regulations and offers technical support for industrial applications requiring this barium compound.
