Preparation and characterization of CePO4 coated ZrO2 composite powders by Hydrothemal method Jing Wang Xin Wang* Wenlai Zhang Qiuju Zheng Jihui Xu (Institute of Materials Science and Engineering, Ocean University of China, Qingdao China,266100) E-mail address: wangjing8354@yahoo.cn; wangxinhd@ouc.edu.cn Keywords: hexagonal monoclinic hydrothemal method Abstract: The hexagonal and the monoclinic CePO4 with rod-like coated ZrO2 composite powders were successfully synthesized through the hydrothemal method. the coated powders were characterized by the techniques of XRD, TEM, DTA and zeta potential measurements.
In addition, the morphology of the coated powders after calcinations at 1000°C was also investigated. 1.Introduction Ceramic materials have been used as engineering materials because of their high strength and high hareness.
In order to improve the machinability of this ceramic materials, one metrod is to introduce another weak interphase or layered structure material into the matrix to facilitate crack deflection during machining[3].

The Duncan-Change model is a nonlinear elastic model which was widely accepted by the geotechnical community in approximating the constitutive response of geo-materials.
Previous experimental research using triaxial tests The triaxial test is one of widely-used tests for discovering the constitutive law in geo-materials.
They performed triaxial tests on methane hydrate-bearing sands and achieved useful information on the stress-strain response of those materials.
