Study on Properties of 9Al2O3·2B2O3 Whisker Reinforced PZT95/5 Type Ferroelectric Transitional Ceramics

Abstract

Abstract: 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) Whisker pulling and bridging play important roles in the process of reinforcing.

Key words: whisker, reinforce, PZT95/5, mechanical properties, electric properties
