White color toughened zirconia ceramic guide plate high strength 95% zro2 plates sudstrate
Ceramic Substrates are used in many electronic applications where a thin insulating layer of thermally stable material
is required to conduct heat away from electronic components whilst electrically insulating them, and material is 95%,
96%, 99% alumina and zirconia.
Properties with excellent insulation, high mechanical strength, high thermal conductivity, low expansion coefficient,
small dielectric constant, high-temperature resistance, excellent erosion and wear resistance, good quality in chemical
shock heat and cold.
Advantages of Zirconia ceramic guide plate:
2. Self Lubricating.
3. Long Service Life.
4. Good Polished Surface.
5. Environmental and Healthy.
6. Superior Mechanical Strength.
7. High Corrosion and Wear Resistance.
8. Good Insulation Performance Precision.
9. High Temperature and Pressure Resistance.
10. High Purity Zirconia and Alumina Ceramic Material.
The products are made of zirconia ceramic and alumina ceramic material, which have
advanced and excellent performances.
