Introduction:
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.
Barium titanate has many important commercial applications. It has both ferroelectric and piezoelectric properties. Also, it has a very high dielectric constant (about 1,000 times that of water). The compound has five crystalline modifications, each of which is stable over a particular temperature range. Ceramic bodies of barium titanate find wide applications in dielectric amplifiers, magnetic amplifiers, and capacitors. These storage devices are used in digital calculators, radio and television sets, ultrasonic apparatus, crystal microphone and telephone, sonar equipment, and many other electronic devices.
