Application

Barium titanate serves a critical function in the realm of electronic ceramics, largely due to its unique ferroelectric, piezoelectric, and dielectric properties. This white crystalline solid is key in manufacturing ceramic capacitors and various electronic devices like actuators, sensors, ultrasonic generators, and piezoelectric transducers. The application of barium titanate extends to dielectric amplifiers, memory devices, and other computer elements due to its role as a semiconductor with a positive temperature coefficient of resistivity. It is particularly valued for its high permittivity, making it an essential component in capacitors with superior performance, especially when doped. The potential for significant energy savings through reduced temperature sintering has been explored, particularly for Low Temperature Co-fired Ceramics (LTCC) applications. By integrating silicate glass systems or adding materials like boron oxide, barium titanate can achieve substantial density even when sintered at lower temperatures, such as 900°C for 8 hours, illustrating its adaptability and efficiency in technological advancements.
