摘要

Many studies have been published on MgO-Al2O3-SiO2 (MAS) glass and glass-ceramic composition. Because MAS glass-ceramics are materials with excellent mechanical properties such as high strength, high Young’s modulus, and low expansion coefficients. The cordierite phase is the main phase of MAS glass-ceramics and provides high-strength properties to this type of glass-ceramics. In this study, excess ZrO2 and Bi2O3 were added to the MAS composition prepared stoichiometrically from magnesite waste, quartz, kaolin, and alumina. Kissinger, Augis–Bennett, and Ozawa methods investigated the crystallization properties of the prepared MASBZ- and MASB-coded compositions. The mechanical properties of the material were also investigated in the study.
