A Preliminary Study on Composition Optimization of an Industrial Glass-Ceramics Based on Cluster-Plus-Glue-Atom Model
The cluster-plus-glue-atom model proposed by our team identifies the structural unit that carriers the composition of any structure.Specifically,for silicate glasses,the composition unit is composed of 16 trivalent-cation { M2O3 } and quadrivalent units { Si2O4 }.In this work,an industrial glass-ceramic product MT3A was optimized by the cluster-plus-glue-atom model,and the glass was prepared and crystallized.Finally,the structure and properties of the sample were characterized.Among the transparent glass-ceramics thus obtained,MT3C and MT3D show optical transmittance of 89％and 92％,flexural strength of 155 and 134 MPa,and hardness of 652 and 655 HV,respectively.
