Uniaxial tensile strength tests were carried out on several engineering ceramics in air at temperatures ranging from room temperature up to 1600℃. The material chosen for the present study were silicon nitride,silicon carbide and partially stabilized zirconia ceramics, which are in the process of development for gas turbine applications. The tensile strength of silicon nitride rapidly decreased at temperature above 800〜1000℃. When the temperature rose as high as 1300℃, the strength decreased to about 10 percent of the room temperature strength. On the other hand, the strength of silicon carbide did not change appreciably with temperature. The strength of zirconia decreased with increasing temperature; at 1000℃ the strength was reduced to 8 percent of the room temperature strength.
