| Research Abstract |
Fabrication research such as new Al2O3/Sm2O3system, Al2O3/Nd2O3system and Al2O3/La2O3system containing phases with a perovskite structure have been conducted by using FZ furnace.We developed a new high temperature structural material of Al2O3/SmAlO3system having excellent high temperature characteristics at 1600.C in an air atmosphere. At a test temperature of 1600.C, the flexural strength is 710-760 Mpa and approximately 60 times higher than 11.4 MPa of the sintered composite with the same chemical composition. The MGC material also showed the greater thermal stability, with no grain growth and no change in mass after an exposure of 500 h at 1600.C in an air atmosphere.
