Study on Lead-Free Electroceramics - Piezoelectric Materials Focusing on Crystalline Orientation -

Lead free in electroceramics industry is described and new fibrous piezoelectric materials are explained as an original work. Reduction of lead has strongly been promoted in electroceramic devices. Due to this promotion, the amount of lead has actually decreased. However, in piezoelectric devices, PZT whose main material is lead oxide is dominantly used. Although many study and development for alternative materials have been done, the decisive material has not been obtained. In this paper, the recent development trend of lead-free in electroceramic industry is reviewed, and then synthesis of new fibrous piezoelectric materials by the present author is explained
