Product Description

White Yttria Stabilized Zirconium Oxide Ceramic Plate Zirconia Ceramic Substrate


Introduction of Zirconia Ceramic Substrates

Jinghui Ceramic is a professional manufacturer of zirconia ceramic substrates. It provides one-stop services from molding to sintering to machining to finished products. Welcome to contact us.

Zirconia ceramics have high toughness, high flexural strength, high wear resistance, excellent thermal insulation properties and the thermal expansion coefficient close to that of steel. Zirconia ceramic substrates have obvious advantages, such as strong mechanical properties, high temperature resistance, corrosion resistance, low thermal conductivity, and high insulation.


Molding Technique of Zirconia Ceramic Substrates

At present, injection molding, dry pressing and tape casting are usually used to pruduce zirconia ceramic substrates.

(1) Injection molding is only suitable for forming thick substrates with thicknesses more than 1mm.
(2) Dry pressing often causes delamination of the green body due to uneven radial and axial pressure distribution during the molding process.
(3) Tape casting is suitable for producing thin ceramic substrates with thicknesses from 0.2mm to 3mm. The have the advantages of fast production speed, high degree of automation, uniform structure and good product quality.

The molding process used for our bare zirconia ceramic substrates is tape casting. Below is the process flow.
