Abstract

The formation mechanism of ZrSiO4 powders from ZrO2 and colloidal SiO2 sols has been studied. The change in the ZrSiO4 yield rate with seeding and non-seeding has also been investigated. The induction period of the ZrSiO4 yield-rate curve corresponded to the n=1 region, a simple nucleation region, on the Avrami plot. The n=1 region was a rather wide range at 1200–1300°C and the nucleation reaction was promoted in this temperature range. It was found that the ZrSiO4 yield rate became high, even if seeding was not used, when the heating rate was controlled at less than 1 °C min−1.
