2. Role and reduction of lead in Leadfree in electroceramics industry is described and electroceramics new fibrous piezoelectric materials are explained as an original work. Reduction of lead has strongly been Different from solder, lead oxide is used for promoted in electroceramic devices. Due to this electroceramic materials instead of metal. Both oxide promotion, the amount of lead has actually decreased. powder and glass forms becomef n nmatenials or aowever, in piezoelectric devices, PZT whose main additives. General role of lead oxide is achievement low material is lead oxide is dominantly used. Although many sintering temperature. As is usual in multilayer ceramic study and development for alternative materials have devices cofiring with low melting point metals such as been done, the deve l hsnt been obtain silver and copper requires low sintering temperature of In this paper, the recent development trend oflead-free In ceramics. In this case, lead oxide in the form of oxide electroceramic industry is reviewed, and then synthesis of powder and glass is quite useful. However, alterative new fibrous piezoelectric materials by the present author method has established because the recent trend of is explained. elimination of lead has improved effectively.Occasionally, lead containing glass is used for glass fit to achieve strong adhesion of terminal electrode with
