Product Description

High Hardness Polished ZrO2 Zirconium Oxide Substrate Zirconia Ceramic Sheet

Introduction of Zirconia Ceramic Substrates

In terms of functional ceramics, zirconia ceramic substrates are used as induction heating tubes, refractory materials, and heating elements due to their excellent high temperature resistance.

Zirconia ceramics have sensitive electrical parameters, high toughness , high flexural strength and high wear resistance , excellent heat insulation performance, and the thermal expansion coefficient close to that of steel. They are mainly used in oxygen sensors, thermal substrates for fuel cells, solid oxide fuel cells and high temperature heating elements and other fields.

Why Polished?

Three major benefits of lapping and polishing for the ceramic substrate:

1. A finer pattern can be obtained.

2. Better parallelism of the upper and lower surfaces (thickness tolerance) can be achieved.

3. A thinner metallization layer can be acquired.
