It is known that sintering of pure lead magnesium niobate (designated PMN) powder requires relatively high temperature (>1100°C) and the latter necessitates the use of costly high palladium based electrode for multilayer capacitors. Here, we have shown that PMN can be rapidly sintered at 900°C (30 min soaking) by using 2–3 wt% excess PbO. However, appreciable densification by the aforesaid method is only possible when the particle (aggregate) size of the PMN powder is quite large (≥ 15 μm). Possible reasons for such behaviour have been delineated.
