Article Preview

Ceramics of morphotropic phase boundary (MPB) Pb(Mg1/3Nb2/3)O3-PbTiO3 have been processed from powders synthesized by mechanochemical activation of oxides. Their properties have been characterised and are compared with those of a MPB Pb(Mg1/3Nb2/3)O3-PbTiO3 ceramic material by the columbite route. Current experiments on texturing by templated grain growth from the powders synthesised by mechanochemical activation are briefly described. MPB Pb(Zn1/3Nb2/3)O3-PbTiO3 has also been mechanosynthesised, though perovskite is not stable under heating and ceramics cannot be processed. Pb(Fe1/2Nb1/2)O3 is being investigated as a means of stabilising the perovskite, and MPB ceramic materials of the ternary system have been successfully prepared.
