Abstract
Ba4-2xAg2+xYxNb10O30 (where x = 0.0, 0.1, 0.3 and 0.5) ceramic composi tions have been prepared and the effect of yttrium on dielectric and p iezoelectric properties of barium silver niobate (BAN) studied. The pr epared materials are characterized by using SEM and XRD techniques. Di electric measurement indicated a decrease in curie temperature of yttr ium substituted BAN. Electromechanical coupling coefficient has been f ound to be more than 0.5. Yttrium substitution in BAN inhibited the gr ain growth.
