Abstract

A high frequency microwave processing technique was used to crystallize lithium disilicate (LS2) stoichiometric glass. A gyrotron system with 30 GHz microwave frequency was used in the crystallization process of LS 2 glass. The glass was prepared by a regular melting and casting process using LS2 glass frit. Thermal analysis of the prepared bulk glass was done to determine the nucleation and the crystallization temperatures. One stage heat-treatment crystallization regime was used to crystallize the studied LS2 glass into glass-ceramic material using both 30 GHz microwave processing and conventional processing. The conventional crystallization was done in an electrical furnace. Characterization of the crystallized glass-ceramic samples was performed using X-ray diffraction (XRD), and scanning electron microscopy (SEM). High frequency (30 GHz) microwave processing was successfully used to crystallize LS2 glass.
