Description

Zirconium Oxide Ceramic Substrates

Zirconium dioxide (ZrO2) is a material that combines a number of excellent physical and mechanical properties, such as:

  • High resistance to destruction;
  • High coefficient of thermal expansion;
  • Low thermal conductivity (relative to other types of ceramics);
  • High bending strength and tensile strength;
  • High resistance to wear and corrosion.

Due to the high coefficient of thermal expansion, zirconium dioxide is often used as a matching material. Also, the coefficient of thermal expansion of this type of ceramics is very close to the coefficient of thermal expansion of metals, for example copper, due to which there is no need for special matching layers between the metallized layer and the substrate.
ZrO2 substrates have excellent resistance to cracking, strength and high impact strength, which makes them indispensable for use in devices operating under mechanical stress.
Due to the relatively low thermal conductivity, ceramics based on zirconium dioxide is an excellent heat insulator.
Also, some types of ceramic substructures, depending on the percentage of zirconium dioxide, have a remarkable property - oxygen conductivity. Which is actively used to measure the oxygen content in lambda probes.
