Description and Uses
Barium titanate (BaTiO₃) is an inorganic compound that appears as a white powder but turns transparent when crystallized into larger structures. With its characteristic ABO₃ perovskite lattice, this functional ceramic material serves as a critical raw material for the electronic ceramics industry. Owing to its exceptional ferroelectric, piezoelectric, and dielectric properties, along with high insulation resistance, it is extensively employed in multilayer ceramic capacitors (MLCCs), positive temperature coefficient (PTC) thermistors, optoelectronic devices, and memory components.
Attributing to its ferroelectricity, barium titanate is applied as a semiconductor with positive temperature coefficient of resistivity. It is one of the most important electroceramic materials among all the ferroelectric materials. Barium titanate has also dielectric properties, which can be used in the manufacture of ceramic capacitors. Furthermore, barium titanate has piezoelectric property and can be used in electrical devices such as actuators, accelerators, ultrasonic generators, piezoelectric transducers, filters, and sensors.
In electronic devices, e.g., as voltage-sensitive dielectric in so-called dielectric amplifiers, in computer elements, magnetic amplifiers, memory devices.
