Abstract
Novel nanoporous silica aerogel impregnated highly porous zirconia ceramics were successfully synthesized from silica gel and camphene-based freeze-cast porous zirconia ceramics. The resultant porous ceramic–aerogel composites exhibited high compressive strength of 36.8 MPa, and ultra-low thermal conductivity ranging from 0.041 to 0.098 W m−1 K−1, as the porosity increased from 46.5% to 69.8%. The present work provides an efficient way to fabricate high-strength thermal insulation materials with ultra-low thermal conductivity.
