Cerâmicas de titanato e zirconato de chumbo dopadas com neodímio foram sinterizadas em um forno de microondas de uso doméstico modificado. Neste tipo de aquecimento, a energia eletromagnética é transferida diretamente para o material, sendo convertida em calor pelo material cerâmico, reduzindo o tempo e energia durante o processamento.
