High Toughness Yttria Stabilized Zirconia Ultra Thin Ceramic Sheet
Introduction of Zirconia Ceramic sheet
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.
Advantages of Zirconia ceramic sheet
1. Strong mechanical properties.
2. High temperature resistance.
3. Corrosion resistance.
4. Low thermal conductivity.
5. High insulation.
Molding Technique of Zirconia Ceramic Sheet
At present, injection molding, dry pressing, and tape casting are usually used to produce zirconia ceramic substrates.
1. Injection molding is only suitable for forming thick, more than 1mm thick substrates.
2. Dry pressing often causes delamination of the green body due to uneven radial and axial pressure distribution during molding.
3. Tape casting is suitable for producing thin ceramic substrates with thicknesses from 0.2mm to 3mm. They have the advantage 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.
