Paper Title:
Thermal Properties and Microstructure of Zirconia/Monazite-Type LaPO4 Composites for Powder Preparation Methods
  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.
