Abstract: 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.
