Both Si3N4 and SiC in their dense forms are leading candidate ceramics for gas turbine components because of their unique physical properties that minimize the thermal stresses which develop during gas turbine operation and their ability to resist oxidation at high temperatures. The purpose of this paper is to present current property data for both materials that are required to calculate thermal stresses, i.e., strength, Young’s modulus, Poisson’s ratio, thermal expansion, thermal conductivity, and specific heat.
