Synthesis and sintering of nanocrystalline barium titanate powder under nonisothermal conditions. II. Phase analysis of the decomposition products of barium titanyl-oxalate and the synthesis of barium titanate

Abstract

The effect of heating rate on the phase composition of decomposition products for barium—titanium oxalate under isothermal conditions is studied. The mechanism of BaTiO3 synthesis changes with heating regime. Features of nonlinear heating regimes are considered: rapid heating during both decomposition of crystal hydrates and in ultrafine mixture of titania, baria, and barium carbonate followed by slow heating while the system moves towards an equilibrium condition.
