چکیده انگلیسی
During freeze casting of TiO2 porous ceramics, the porous architecture is strongly influenced by TiO2 particle size, solids loading, and cooling temperature. This work investigates the influences of particle size, freezing substrate, and cooling temperature on the TiO2 green bodies prepared by freeze casting. The results show that the lamellar channel width with 100Â nm particles is larger than that of 25Â nm particles, yet the ceramic wall thickness is noticeably decreased. The lamellar structure is more ordered when using a copper sheet than glass as its freezing substrate. A finer microstructure results when frozen at â 50Â â than â 30Â â. Such porous materials have application potentials in a wide range of areas such as photocatalysis, solar cells, and pollutant removal and should be further studied.
