| Abstract: | A fabrication process has been developed which allows to obtain pyrochlore free lead magnesium niobate ceramics with a low sintering temperature (～ 900–1000°C). The elimination of the pyrochlore phase improves dielectric characteristics and compositions which a Curie temperature of around room temperature show high dielectric constants (15–25000). |
