bstract
camphene-based freeze-casting method was adopted to create ceramics with aligned, equiaxed pores applied so far exclusively for ceramics—is
emonstrated for ZrO2 porous ceramics. The pore volume fraction, channel size and pore shape were controlled by varying the freezing temperature,
olid content and sintering condition. After sublimation of camphene, the samples were sintered for 2 h at elevated temperatures ranging from 1400
o 1550 ?C. The initial level of solid loading played a primary role in the resulting porosity of the product. The porosity decreased from 82.5 to
5.5 vol.% when the solid loading was increased from 10 to 20 vol.%. The relationship of the compressive strength versus initial solid loading and
intering temperature was discussed. This technique is considered potentially useful in fabricating novel porous ceramics with special structure,
nd introduces a new application field of freeze-casting.

. Introduction
High performance ceramics containing tailored porosity
xhibit special properties and features that usually cannot
e achieved by their conventional dense counterparts. The
otentialities offered by highly porous ceramics are attracting
onsiderably more attention today than just a few years ago.1,2
eramics with low density (high porosity) can be engineered
