Pure and iron-doped bismuth sodium titanate (BNT) ceramics were successfully produced using solid-state sintering. Substitution of Fe 3+ onto the B-site occupied by Ti 4+ can create oxygen vacancies which thereby enable lower sintering temperatures of 900 °C and higher densification at up to 97% of relative density.Web
