Zircoa has a large choice of different alumina and zirconia compositions.

If you like to know more about our materials please do not hesitate to contact us.

The key properties of zirconia are:

high density (higher than other ceramic, lower than tungsten carbide or steel)
high fracture toughness
high operating temperature (> 2,300 °C / 4,200 °F)
very low thermal conductivity
oxygen ion cunductivity

high corrosion resistance

good impact resistance

good wear resistance

non wet by molten metals (except Titanium)

relatively good thermal shock resistance
