Synthesis of $(ZrSiO_4)$ Powders by the Sol-Gel Process -Effect of the Milling-

ABSTRACT

ZrSiO4 powders were prepared from partially hydrolyzed solution of Si(OC2H5)4 and ZrOCl2.8H2O solution by the sol-gel method and formation rate of ZrSiO4 on the reaction parameter was investigated. In order to prepare homogeneous ZrSiO4 precursor gels, the H2O/Si(OC2H5)4 molar ratio of about 2, the pH of the ZrOCl2.8H2O solution fo about 4 and stirring time of the mixed solutions of about 2 hrs were appropriate. Formation of temperature of ZrSiO4 reduced about 15$0^{circ}C$ by milling and formation of ZrSiO4 at 1300~135$0^{circ}C$ showed an accelerative increase through the hedvall effect by silica.

Key words: Zircon, $Si(OC_2H_5)$, $ZrOCl_2
