Zirconia ceramic plates is made of zirconium oxide materials, it is a commonly used technical ceramic material. It has relatively high fracture strength among all ceramic materials, with the addition of high hardness and low friction coefficient, it is usually used for structural ceramic components. Its thermal expansion coefficient is similar to steel, so it can be jointed to steel parts. Besides, zirconia ceramic plates has excellent corrosion resistance and low thermal conductivity.
Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.
Less variance in outline, plate thickness, slit pitch, etc.
Minimal warpage, bending, and undulation.
Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.
Superior mechanical strength. Products with higher mechanical strength are also in our lineup.
Excellent resistance against oil and chemical.
Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.
