摘要: 本团队提出的团簇加连接原子模型从结构根源上揭示了硅酸盐玻璃的成分载体,即硅酸盐玻璃的成分式由总数为16个的三价单元{M2O3}和四价单元{Si2O4}构成。本工作引入该模型,对一种工业微晶玻璃MT3A进行了成分优化,并进行玻璃制备和晶化,最后对样品进行结构和性能表征。在获得的新的透明微晶玻璃中,MT3C的透过率为89%,抗弯强度和硬度分别为155 MPa和652 HV;MT3D的透过率为92%,抗弯强度和硬度分别为134 MPa和655 HV。

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.
