AbstractWe report a novel yttria-stabilized zirconia (YSZ) fiber reinforced highly porous gamma-(Y0.8Ho0.2)(2)Si2O7 material that provides multifunctional thermal insulation and microwave-transmitting capability. Through the fiber reinforcement and solid solution strengthening modifications, the porous ceramic demonstrates extremely high porosity (93.2%), high compressive strength (1.21 MPa), low dielectric constant (1.39 to 1.37) and low loss tangent (3.0 x 10(-2) to 3.5 x 10(-2)) from 7.2 to 19.5 GHz at 1000 degrees C, low thermal conductivity (0.077 to 0.206 W/(m center dot K) from 25 to 1200 degrees C) and low thermal cycling shrinkage (<0.6% at 1550 degrees C for 2 h).
