Abstract
Thermal conductivity and microstructure of 3YSZ/monazite-type LaPO4 composites
were investigated. Powders were prepared by two kinds of preparation methods such as
conventional ball-milled and chemical precipitation of LaPO4 on the zirconia powder surface.
Thermal conductivity of 3YSZ/monazite-type LaPO4 composites was lower than that of 3YSZ. That
of 3YSZ/monazite-type LaPO4 composites was influenced on the powder preparation methods and
as a function of measured temperature. Microstructure of 3YSZ/monazite-type LaPO4 composites
was not much affected by the amount of dispersed LaPO4 particles. 3YSZ/monazite-type LaPO4
composites were observed to pores after thermal etched. The pore of synthesized specimens was
observed remarkably in compared with conventional ball-milled specimens.
