Abstract
A low‐temperature, single step, reactive sintering method for Pb(Mg1/3Nb2/3)O3 (PMN) and PMN–PbTiO3 (PMN–PT) processing was developed based on the coating of Mg(OH)2 on Nb2O5. This method simplified the processing of PMN and PMN–PT to a single step of heat‐treatment and decreased the sintering temperature to 1000°C. It was found that the pyrochlore phase formation reaction at 500°C reduced the particle size to 130 nm. The overlap of the pyrochlor‐perovskite phase transformation between 700° and 900°C and the densification process between 800° and 1000°C improved the sintering process. These two factors were the major reasons of the low temperature sintering.
