Description

Barium Oxide CAS NO 1304-28-5 is a white to yellowish-white solid inorganic compound with significant industrial utility. It serves as a powerful dehydrating agent and a key precursor in the synthesis of other barium compounds and specialty glasses. This material is essential for manufacturers and researchers in sectors requiring high-purity chemical intermediates, robust desiccants, or specialized ceramic components.

Application

• Desiccant/Drying Agent: Used for drying gases and solvents due to its strong affinity for water and carbon dioxide.
• Glass & Ceramics Manufacturing: A vital component in the production of optical crown glass, ceramic glazes, and enamels to modify refractive index and thermal properties.
• Chemical Synthesis: Acts as a precursor for producing other barium salts, such as barium carbonate and barium hydroxide, and in organic synthesis as a catalyst or reactant.
• Cathode Ray Tubes & Electronics: Historically used in the manufacture of CRT glass and in certain electronic ceramics.
• Fuel Cell & Catalyst Systems: Investigated for use in solid oxide fuel cells (SOFCs) and as a catalyst support or promoter.
• Laboratory & Research: Employed in analytical chemistry and materials science research for its specific chemical properties.

Quality Control

Our Barium Oxide is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and reliability. We offer material that meets technical and high-purity grade specifications, with critical parameters including assay, moisture content, and impurity profiles rigorously controlled. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area. Keep the container tightly sealed under an inert atmosphere or with appropriate desiccant to prevent reaction with atmospheric moisture and carbon dioxide. Store away from incompatible materials such as strong acids.
