Porous Y2SiO5 ceramic was fabricated by freeze casting with tert-butyl alcohol as solvent. The porous Y2SiO5 ceramic possessed long straight pore structure. With decreasing solid loading from 20 to 10 vol.%, the porosity of the Y2SiO5 ceramic increased linearly from 45% to 72%, while the compressive strength declined from 23.2 to 3.1MPa. The thermal conductivity of Y2SiO5 decreased from 1.34W/mK for the dense bulk to 0.05 W/mK for the porous body with a porosity of 57%.
