Uniaxial tensile strength tests of engineering ceramics were carried out in air at temperatures ranging from room temperature up to 1600C. The ceramic materials chosen for tensile tests were selected as representing existing and developing silicon nitride, silicon carbide and partially stabilized zirconia materials technology, suitable for gas turbine applications. The tensile strength of silicon nitride rapidly decreased at temperatures above 800～1000C. When the temperature increased to as high as 1300C, the strength decreased to about 10 percent of room temperature strength. On the other hand, the strength of silicon carbide did not change appreciably with temperatue. The strength of zirconia decreased with increasing temperatues. At 1000C the strength was reduced to 8 percent of room temperature strength. Observations of the fracture origin and of the crack propagation on the fracture surfaces were made and discussed.
