| Introduction Crystallization is a well-recognized practical means of improving the brittleness of glass. Many glass-ceramics have been investigated, and some have been incorporated into practical materials. Glass-ceramics in the MgO–Al2O3–SiO2 (MAS) system have attracted much interest on account of their superior mechanical and thermal properties, i.e., high strength and stability at high temperatures. To investigate the effect of nucleating agents, this study investigates the crystallization behavior of an MgO–Al2O3–SiO2-MoO3 glass with high % wt molybdenum oxide and low % wt nickel oxide addition. Under a not reducing condition, crystals formed in the bulk of the super cooled liquids, whereas melting in air yielded only surface crystallization. The purpose of using of Nickel oxide as nucleating to modify the mechanical properties, is based on the manipulation of the grain size during the solidification process. The first crystalline phase precipitated inside the glass was α-cordierite and β-cordierite in glasses doped with nickel oxides. Nickel oxide yielded a finer microstructure of the glass-ceramic. | |
