Researches Concerning Phase Transition of Zirconium Titanate Prepared by Electrolytic Method
Keywords:
zirconium titanate, electrodeposition, phase transition, structure
Abstract
Powder zirconium titanate ceramics obtained by an electrolytic method has been investigated. Continuous phase transition were found to occur in powder zirconium titanate above and below a major discontinuity at 1120 oC ± 10 oC. The phase transition is characterised by a decrease in the length of the longest unit-cell dimension, on conversion of the high-temperature form to the low-temperature structure. The unit-cell volume decreases continuously and linearly with decreasing temperature.
