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 plates have obvious advantages, such as strong mechanical properties, high temperature resistance, corrosion resistance, low thermal conductivity, and high insulation. There are irreplaceable applications.
At present, injection molding, dry pressing and tape casting are usually used to pruduce zirconia ceramic plates.
Below is the process flow of our zirconia ceramic plates.
Do the Bare Ceramic Substrates Meet the Requirements for Metallized Ceramic Substrates?
Yes. Metallized ceramic substrates, also known as metallized ceramic circuit boards, include bare ceramic substrates and metal circuit layers. Bare ceramic substrates are widely used in integrated circuit packaging, LED lighting, heat dissipation substrates and other fields in the electronic industry due to their advantages of thinness, high temperature resistance, high electrical insulation performance, low dielectric loss, and good chemical stability.
