Mechanical Properties and Microstructure of Layered LaPO4 Ceramics
层片状LaPO4陶瓷的力学性能与显微结构

Dense and layered LaPO4 ceramics were fabricated by using pressureless sintering, hot pressing and spark plasma sintering . Densification, texture and mechanical properties of LaPO4 ceramics by different sintering routes were characterized . Based on the formation of weak interface of Al2O3 and LaPO4 phase, machinable 40wt%Al2O3/LaPO4 composite having a hardness of 6.3±0.45GPa, was fabricated and characterized by using cemented carbide drill.
