Abstract

In this study, 5 um sized ZrSiO4 was ground to 1.9 um, 0.3 um, and 0.1 um sized powders by wet high energy milling process, and the sintering characteristics were observed. Pure ZrSiO4 itself can-not be sintered to these levels of theoretical density, but it was possible to sinter ZrSiO4 powder of nano-scale size of, –0.1 um to the theoretical density and to lower the sintering temperature for full density. Also, the decomposition of ZrSiO4 with a size in the micron range resulted in the formation of monoclinic ZrO2; however, in the nano sized range, the decomposition resulted in the tetragonal phase of ZrO2. So, it was possible to improve the sintering characteristics of nano-sized ZrSiO4 powders.
