Product Description

0.3mm 0.5mm 1mm White YSZ ZrO2 Substrate Zirconia Ceramic Plate


Introduction of Zirconia Ceramic Substrates

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. There are irreplaceable applications.


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 zirconia ceramic substrates is tape casting. Below is the process flow of our bare zirconia substrates.
