ABSTRACT

The glass-ceramic of Li2O-Al2O3-SiO2 system was synthesized by using ZrO2, ZrSiO4, ZrOCl2 and Zr(SO4)2, which is a raw material of Zr serving as a nucleation agent. It was confirmed that Avrami parameter of these four glasses is over 3 for bulk crystallization. The glass synthesized by ZrOCl2, and Zr(SO4)2 showed high melting quality during the melting process. It is also observed that the Zr component is uniformly distributed in the glass. Various characterizations was evaluated, including composition analysis and bending strength.
