Robust phase determination in complex solid solutions using diffuse multiple scattering

A novel methodology is presented for identifying and distinguishing between structural phases in multi-phasic systems, such as piezoelectric materials like PMN–PT [Pb(Mg(1/3)Nb(2/3))O(3)–PbTiO(3)], PIN–PMN–PT [Pb(In(1/2)Nb(1/2))O(3)–Pb(Mg(1/3)Nb(2/3))O(3)–PbTiO(3)] and PZT [Pb(Zr,Ti)O(3)], using dif...

Sumario:A novel methodology is presented for identifying and distinguishing between structural phases in multi-phasic systems, such as piezoelectric materials like PMN–PT [Pb(Mg(1/3)Nb(2/3))O(3)–PbTiO(3)], PIN–PMN–PT [Pb(In(1/2)Nb(1/2))O(3)–Pb(Mg(1/3)Nb(2/3))O(3)–PbTiO(3)] and PZT [Pb(Zr,Ti)O(3)], using diffuse multiple scattering and Kossel line diffraction techniques. The method exploits the splitting of triple line intersections from special coplanar reflections combined with logical constraints to generate a splitting fingerprint for robust crystallographic phase determination and discrimination.
