CERAMIC MATERIAL

摘要

Hardness, ageing resistance, wetting behaviour in relation to water and high thermal conductivity are known characteristics of sintered moulded bodies consisting of aluminium oxide; high strength and a high resistance to cracking, i.e. damage tolerance, are known characteristics of sintered moulded bodies consisting of zirconium oxide. To obtain a ceramic material, in which all said characteristics are combined, the invention discloses a material composed of a large fraction of aluminium oxide, zirconium oxide and optionally strontium aluminate.
