The crystallization behavior and microstructural change in glass-ceramics with a cordierite composition were analyzed as a function of concentration and etching time of the HF solution in order to enhance the degree of crystallinity of the glass. Compared to a specimen without etching, the glass frit specimens etched with HF solution showed increased crystalline peak intensities of the μ-cordierite phase in the XRD pattern. The crystal size in the glass matrix also increased with an increasing concentration of the HF solution for the etched glass frit. The crystal peak intensity of the α-cordierite phase in the glass-ceramics made with glass frit etched with 0.5-1.5 wt% HF solution had a slightly higher value than that of pure glass frit regardless of the etching time. The intensity of the specimen with etched glass frit with 3.0 wt% HF solution, however, was lower than that of the specimen of the pure glass frit. Obviously, for the glass-ceramics etched with HF solution of various conditions, the α-cordierite phase is more favorable for crystallization than the α-cordierite phase. This study revealed that the microstructure and ratio of the crystallinity of the α-cordierite phase over the α-cordierite phase in the obtained glass-ceramics could be controlled by changing the HF-etching conditions followed by a heat treatment process.
