Product Description
Calcium Zirconate
Product Introduction
Calcium Zirconate (CaZrO₃) is a high-performance ceramic material known for its outstanding dielectric properties, thermal stability, and chemical inertness. As a perovskite-type oxide, CaZrO₃ is widely used in the production of ceramic capacitors, multilayer ceramic devices, and high-temperature electronic components.
This advanced ceramic powder exhibits a high dielectric constant, low dielectric loss, and excellent thermal and chemical resistance, making it suitable for demanding applications in power electronics, RF modules, and telecommunications. Its high sinterability and phase stability allow for consistent performance under varying thermal and electrical conditions.
Calcium Zirconate also features compatibility with other ceramic materials, allowing it to be doped or blended to enhance specific properties. It is commonly used as a dielectric layer material or insulating medium in multilayer ceramic capacitors (MLCCs), where reliability and long service life are essential.
