Barium titanium oxide, high surface area, Thermo Scientific Chemicals

Description

Barium titanium oxide is a dielectric ceramic widely used in multi-layer ceramic capacitors (MLCCs), embedded decoupling capacitors (EDC) and ceramic filters. It is a piezoelectric and ferroelectric component used in microphones and transducers. It is also useful for thermistors and self-regulating electric heating systems. It is doped with small amounts of metals like scandium, yttrium, neodymium, samarium to become a semiconductor. It is used in some types of uncooled sensors for thermal cameras and in electric vehicles.
