Original Reaction Sequence of Pb(Yb_1/2Nb_1/2)O₃-PbTiO₃: Consequences on Dielectric Properties and Chemical Order

Figure 2

Real part of the dielectric constant (line) and losses (dotted line) of PYN-PT with 60% PbTiO₃ measured at 1 kHz and as a function of temperature on ceramics obtained by various synthesis techniques: +PVA, +1 wt% PbO, and +3 wt% PbO designate the binder used with powders obtained by the solid-state technique. All samples were sintered at 950°C.
