Synthesis and Sintering of Nanocrystalline Barium Titanate Powder Under Nonisothermal Conditions. IV. Electron Microscope Study of the Evolution of Barium Titanate Powder Morphology

摘要

The dependence of BaTiO3 powder morphologyevolution during decomposition of barium titanyl-oxalate andsubsequent barium titanate synthesis on heating rate is studied. Itis established that the mechanisms of morphology developmentdepend upon the heating mode and the necessity of a nonlinearheating schedule is proven. This schedule makes it possible toavoid some limitations of linear heating schedule and to use their advantages.
