依据单纯形格子点设计,利用堇青石基质玻璃,低膨胀硼硅酸盐玻璃,熔融石英三种原料组分通过烧结法制备了堇青石基复相微晶玻璃,建立回归模型,并对其吸水率和热膨胀性能进行测试。结果表明:所建模型准确度高,可以准确地预测微晶玻璃的性能;在微晶玻璃单性能下优化时,通过指定性能可以确定原料组分;在双性能下优化时,通过指定的性能范围可以确定原料组分的区域。同理对于多性能,通过性能区域叠加,也可以确定原料组分的组成范围。在双性能优化的区域范围内,选择了一点进行验证实验,证明了实验的可靠性;该研究能给其他研究提供一个借鉴。

According to the design of simplex lattice points,cordierite-based multiphase glass-ceramics were prepared by sintering method using cordierite matrix glass,low-expansion borosilicate glass and fused silica.The water absorption and thermal expansion properties of the glass-ceramics were tested.The results show that the established model has high accuracy and can accurately predict the performance of glassceramic.When glass-ceramic is optimized under the single performance,the raw material component can be determined by specifying the performance.When glass-ceramic is optimized under dual performance,regions of feedstock components can be identified by specifying performance ranges.Similarly,for multiperformance,the composition range of raw material components can also be determined by superimposing performance areas.In the area of double performance optimization,a point is selected for verification experiments,which proves the reliability of the experiments;this research can provide a reference for other researches.
