General description
Application
- 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.
