Abstract
Glass–ceramic powders with a composition of Li 2O·Al 2O 3·4SiO 2 (LAS) containing various ZrO 2 additives have been synthesized by a novel method based on polyacrylamide (PAM) gel process using Al(NO 3) 3·9H 2O, Li 2CO 3, Si(OC 2H 5) 4 and ZrOCl 2·8H 2O as starting materials. X-ray powder diffraction (XRD), thermal analysis (TG–DTA) and transmission electron microscope (TEM) are utilized to characterize the gel powders. For the LAS powders with various amount of ZrO 2, the crystalline phase first obtained is β-quartz solid solution, which then gradually transforms into β-spodumene at high temperature. The transformation from β-quartz solid solution to β-spodumene is increasingly restricted as more ZrO 2 is added in the LAS system. The average particle size of the LAS powders is in nanometer scale with a narrow size distribution.
