Dielectric Material Calcium Titanate Powder

Product Introduction

Calcium Titanate (CaTiO₃) is a high-quality inorganic dielectric ceramic material with a perovskite crystal structure, widely used in the electronics industry for its excellent electrical insulating properties and thermal stability. This advanced ceramic powder is particularly valued in applications requiring stable dielectric performance, such as capacitors, microwave dielectrics, multilayer ceramic components, and insulating substrates.

With a high dielectric constant, low dielectric loss, and good frequency stability, CaTiO₃ powder serves as a key material in dielectric layers and multilayer ceramic capacitors (MLCCs). It provides strong thermal resistance and maintains electrical insulation even at elevated temperatures, making it ideal for use in high-frequency and high-voltage environments.
