Lead titanate thin film synthesis by solid-state reactions

Formation of PbTiO3 thin films on seed layers using DC magnetron layer-by-layer deposition

“…Therefore the formation of the PbTiO 3 phase during annealing passes through two stages: formation of pyrochlore phase from the amorphous mixture and transformation through solid state reaction to the perovskite phase. This leads to thermal stresses and formation of cracks in the films [19]. Therefore the difference between the deposition and annealing temperatures has to be a minimal.…”

“…These include RF magnetron sputtering [8], pulsed laser deposition [9,10], solegel technique [11e14], chemical vapor deposition [15e17], and reactive thermal co-evaporation [18]. Perovskite PbTiO 3 structure with useful properties is formed at relative high temperature (500e600 C) [19]. The other pyrochlore phases occur below 400 C and above 600 C temperature.…”

PbTiO3 thin films grown by mixed reactive thermal co-evaporation

“…Perovskite PbTiO 3 structure is formed at relative high temperatures (400-600 1C) [16]. The others pyrochlore phases (PbTi 3 O 7 , Pb 2 Ti 2 O 7 ) occurs below 400 1C and up to 600 1C.…”

Particle and Crystallite Size Characterisation of Lead Titanate Derived from Solid-state Reaction Method

“…To obtain the stoichiometry, particle and crystallite size PbTiO 3 , different preparation methods have been introduced such as co-precipitation, emulsion or hydrothermal treatment sol-gel and spark plasma sintering sonochemical, besides the conventional solid-state reaction of mixed oxides or mechanical alloying. 4,6,[9][10][11][12]16,20,[23][24][25][26][27][28][29][30][31][32][33][34][35] All methods will produce varying microstructures, processes and then manufacture temperature. The processing time must be determined for quick process and the better quality of final product; it has higher purity in single phase, and the particle and crystallite are formed in nanometer size.…”
