Study on Properties of 9Al_2O_3·2B_2O_3 Whisker Reinforced PZT95/5 Type Ferroelectric Transitional Ceramics

9Al2O3.2B2O3 whisker was used to reinforce PZT95/5 type ferroelectric transitional ceramics.The relation between properties (including electric and mechnical properties) and whisker contentwas studied. Experiment results indicate: (1) Sintering temperature ruduces with the increase ofwhisker content. (2) Composites with proper whisker content can keep electric properties almostas good as that of base material, while their mechanical properties improved. For exemple, thecomposite with 0.3wt% whisker exhibits an increase up to 42.24% in bending strength. (3) Whiskerpulling and bridging play important roles in the process of reinforcing.
