Preparation of nanostructured ZrTiO4 by solid state reaction in equimolar mixture of TiO2 and ZrO2

A solid state reaction in an equimolar mixture of TiO₂ and ZrO₂ was achieved by high‐energy ball‐milling. The ball‐milling first induced the transformation of anatase TiO₂ to high‐pressure phase TiO₂ (II). Nanosized ZrTiO₄ phase was formed from TiO₂(II)/ZrO₂ solid solution by prolonging milling. The finishing of the solid state reaction towards ZrTiO₄ ceramic is investigated in situ at high temperature (< 1100°C) by RS. Reaction is completed at a temperature much lower than reported in literature (1400 – 1600°C). (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
