“…4 Mechanochemical activation (MCA) is an efficient technique for the synthesis of nano-sized ceramic powders such as superconductor, ferrite and ferroelectrics. [5][6][7][8] The advantage of MCA technique is the formation of a single phase directly by mixing the oxides without the necessity for calcinations. 9 By high-energy milling, the particle size of the ceramic powder is greatly reduced, and hence the area of contact between the reactant powders is increased, therefore, the ceramic mixture is formed to a composite with a phase.…”

We synthesized nano-sized (Pb, La)TiO3 powder using a high energy mechano-chemical technique at room temperature. By the results, nano-sized (Pb, La)TiO3 powder with perovskite structure was successfully synthesized from an oxide mixture using a high energy mechano-chemical technique without any post-annealing. The mechanically-synthesized (Pb, La)TiO3 powder consisted of nanometer sized particles and had very high homogeneity. According to increase of milling time, source phases such as Pb oxides and TiO2 disappeared and the perovskite PLT phase was formed by chemical reaction and the release of OH group.

Pressure dependent studies on technologically important ferroelectric material Pb 0.70 Ca 0.30 TiO 3 show the occurrence of a new hitherto unreported pressure dependent phase transition around 4 GPa. In the pressure range 4-14 GPa, the parent tetragonal (P4mm) phase of Pb 0.70 Ca 0.30 TiO 3 transforms in to a monoclinic (Cm) phase before attaining its paraelectric cubic (Pm3m) phase around 15 GPa. High pressure Raman studies reveal the presence of a critical pressure above which the ferroelectric phase starts to reappear in the paraelectric phase. This critical pressure is found to be much lower than the critical pressure observed in pure PbTiO 3 . Possible reasons for this lowering of the critical pressure are presented.
