Leírás

Általános leírás

Barium carbonate is an inorganic compound that is poorly soluble in water. It is used in various industrial applications, particularly in the ceramics industry, where it is used in glazes and as a fluxing agent. It is also used in the manufacture of electronic ceramics, capacitors, PTC thermistors, and other electronic components.

Alkalmazás

Barium carbonate can be used:    

• A precursor for the preparation of BaTiO₃ nanoparticles, a dielectric material which is useful for manufacturing multilayer ceramic capacitors.
• A precursor for the synthesis of barium titanate thin films, which finds applications in photovoltaic devices.

Barium carbonate can also be used in following applications:

• BaCO₃ nanoparticles have been reported as catalysts for high-temperature oxygen reduction reactions (ORR) in solid oxide fuel cells (SOFCs).      
• Barium carbonate-based nanomaterials have been employed for sensor and catalysis applications, with improved sensing performance using one-dimensional nanostructures.    
• BaCO₃ is used to make barium titanate for Multi-layer ceramic capacitor and composite oxides, as well as for PTC thermistors. It′s also used to make optical glass, sputter glass for semiconductors, and as a component of phosphor materials.
