| Abstract | Advanced thermal insulators request excellent properties, including low thermal conductivity, lightweight (high porosity) and high strength. It was a challenge to coordinatively achieve extremely high porosity (>90%) and high strength. We herein report a foam-gelcasting-freeze drying method to process highly porous ceramic. Yttria-Stabilized Zirconia (YSZ) fiber strengthening approach is incorporated to enhance its mechanical property. Our YSZ fiber reinforced porous gamma-Y2Si2O7 ceramic shows very high porosity (92.9%), high compressive strength (1.35 MPa), and extremely low thermal conductivity (0.090 W/(m.K)). The developed highly porous composite is a promising high-temperature thermal insulator. (C) 2017 Acta Materialia Inc. Published by Elsevier Ltd.
