| Abstract |
| Lead magnesium niobate (PMN) is a ferroelectric compound with
relaxor characteristics. PMN powder prepared by semi-wet
hydroxide route was compacted and sintered at 1000 ·c in air
and PbO atmosphere. The loss of PbO, during sintering, leads
to the formation of pyrochlore phase which lowers the dielectric
constant and density of PMN ceramics. The effect of sintering
atmosphere on the dielectric properties and the density of PMN
ceramics is reported in this study. |
