Abstract

The effects of hydrothermal reaction conditions on synthesis

of ZrSiO₄ are studied by orthogonal design∙m （Zr）∶m （Si） of the precursors‚reaction temperature‚reaction time and rate of rising temperature are primary factors∙Under the condition of m（Zr）∶m（Si）＝1∙2∶1∙0of the precursors‚temperature of 335℃‚time of 4h and rate of 1∙6℃／min‚the ultrafine ZrSiO₄ powders are synthesised by hydrothermal method which are wel-l crystallized‚wel-l degree of dispersion and the particle size is less than100nm.

Keywords：hydrothermal synthesis；nanometer ZrSiO₄；technical conditions
