Barium Titanate for carbon powder

Product Description:

Barium Titanate (BaTiO₃) and its derivative compound BaTi₄O₉ are advanced ceramic materials widely used in the electronics and telecommunications industries due to their exceptional dielectric and ferroelectric properties.

BaTiO₃ is a well-known perovskite-structured ceramic with a high dielectric constant, excellent ferroelectric characteristics, and strong piezoelectric behavior. It is commonly used in multilayer ceramic capacitors (MLCCs), thermistors, electro-optic devices, and energy storage applications.

BaTi₄O₉, on the other hand, is a barium-rich titanate ceramic material often utilized in microwave and radio-frequency applications. It offers stable dielectric properties, low dielectric loss, and good thermal stability, making it ideal for microwave dielectric resonators and filter components in high-frequency communication devices.

Both materials are available in powder or sintered form and can be customized to meet specific performance needs in advanced ceramic processing.
