“Thermal Analysis Study of Diol-Based Precursors for Chemical Solution Deposition of 0.7 Pb(Mg1/3Nb2/3)O3-0.3 PbTiO3 Thin Films”
Thermal decompositions of the precursors for chemical solution deposition of 0.7 Pb(Mg1/3Nb2/3)O3-0.3 PbTiO3 thin films were studied. The precursors were prepared from lead acetate or acetylacetone-modified lead acetate by diol-based route, and dried at 100ºC.Thermal decompositions of the PT, PMN an...

| Sumario: | Thermal decompositions of the precursors for chemical solution deposition of 0.7 Pb(Mg1/3Nb2/3)O3-0.3 PbTiO3 thin films were studied. The precursors were prepared from lead acetate or acetylacetone-modified lead acetate by diol-based route, and dried at 100ºC.Thermal decompositions of the PT, PMN and PMN-PT precursors in air occur stepwise. Between room temperature and approximately 200ºC the weight loss of a few % is due to evaporation of residual solvents. Organic groups decompose in the 200 - 400ºC and 400-650ºC ranges. The thermal decompositions are affected by the choice of the Pb-compound and chemical composition of the sample. |
