The liquid-solid mixing method was used to adjust the components of the MSS and glass-ceramics was obtained. The effects of heat-treatment conditions on the microstructure ,physical and mechanical properties of samples were studied. Economical benefits of the novel process were analyzed. The results show that heat-treatment is a very effective approach to achieving crystallization. The dominant crystal phase in products is diopside [ （ Mg6Al2Fe2 ） Ca （ Si1.5 Al5 ） O2 ]. The shape of the crystallization is like a granule. The glass-ceramic samples exhibited good mechanical properties and presented chemical stability. The economic benefits of the process are remarkable due to less energy consumption compared with conventional glass-ceramics production methods.展开更多
