摘要：
Ba4-2xAg2+xYxNb10O30 (where x = 0.0, 0.1, 0.3 and 0.5) ceramic compositions have been prepared and the effect of yttrium on dielectric and piezoelectric properties of barium silver niobate (BAN) studied. The prepared materials are characterized by using SEM and XRD techniques. Dielectric measurement indicated a decrease in curie temperature of yttrium substituted BAN. Electromechanical coupling coefficient has been found to be more than 0.5. Yttrium substitution in BAN inhibited the grain growth.
