| titleOfInvention |
Fully dense alumina ceramic composite reinforced by surface-zirconated alumina fibers |
| abstract |
Alumina fibers whose surface is coated with oxygenated zirconium species chemically bonded to alumina to retain their identity in an alumina matrix when the mixture is sintered at temperatures needed to form a fully dense ceramic. The resulting fully dense ceramic composite shows the beneficial effects of such reinforcing fibers by having increased fracture toughness and thermal shock resistance. |
