Product Application of Barium Titanate CAS#12047-27-7
Barium titanate has a wide range of important commercial applications due to its ferroelectric and piezoelectric properties, as well as its extremely high dielectric constant—approximately 1,000 times greater than that of water. It exists in five crystalline forms, each stable within a specific temperature range. Ceramic materials based on barium titanate are extensively used in dielectric amplifiers, magnetic amplifiers, and capacitors. These components are widely applied in electronic devices such as digital calculators, radios, televisions, ultrasonic equipment, crystal microphones, telephones, sonar systems, and many other technologies.
As one of the most widely used materials in electronic ceramics, barium titanate (BaTiO₃, BT) is particularly valued for its high permittivity, enabling the production of high-performance capacitors through doping. Given its large-scale use in electronic components, reducing its sintering temperature can lead to significant energy savings. For example, in LTCC (Low Temperature Co-fired Ceramics) applications, barium titanate can be sintered at around 1000°C for 24 hours with the addition of a silicate glass system. Additionally, by incorporating boron oxide or lead borate, a sintered body with approximately 90% relative density can be achieved at 900°C over 8 hours.
