Abstract

The formation of perovskite Pb(Mg_1/3Nb_2/3)O₃ (PMN) by the molten salt synthesis method using sulphate flux has been investigated as a function of calcination temperature and mole ratio between Li₂SO₄ and Na₂SO₄. A 97% perovskite phase was synthesized at 750° C for 30 min with 0.635Li₂SO₄-0.365Na₂SO₄ flux without any sub-products affecting the formation reaction of the PMN phase. The percentage of the perovskite phase was influenced by changes in the Li₂SO₄/Na₂SO₄ mole ratio at a given temperature. The pyrochlore phase present was identified as Pb₃Nb₄O₁₃ (P₃N₂) when 0.635Li₂SO₄-0.365Na₂SO₄ flux was used. The results for other lead-based ferroelectrics are also discussed.
