Zirconia ZrO2 Substrate


Zirconia is a sintered ceramic with a really low thermal conductivity that can be used up to 1000°C. It is also the best ceramic regarding abrasion resistance. It is possible to produce parts up to a length of 400 mm.

Characteristics

  • Material thickness: 0,15 – 0,25 – 0,38 – 0,5 mm

  • Formats: 100 x 100 – 200 x 200 mm

Properties

  • High corrosion resistance

  • High abrasion resistance

  • Good electrical isolation

  • Very good gliding properties

  • High planarity

  • Low thermal conductivity

  • Very good mechanical strength
