Zirconia Plate Small Zro2 Ceramic Flat Shim
Zirconia Plate is an advanced ceramics material that is widely used in various industries due to its exceptional properties. It falls under the category of electrical ceramics, which are engineered materials with superior mechanical, thermal, and electrical properties.
One of the significant applications of zirconia plates is in ceramic switch. These switches are used in electronic devices and electrical systems to control the flow of electricity. Zirconia plates are preferred for this purpose because they offer excellent electrical insulation properties and can withstand high voltage without any breakdown.
Advantage:
1. Good electrical insulation
2. Moderate thermal conductivity
3. High corrosion and wear resistance
4. High mechanical strength
5. High compressive strength
6. High hardness
