【摘要】 微晶玻璃的强度是评定材料是否能使用于特定用途的关键。Ｌｉ２Ｏ－Ａｌ２Ｏ３－ＳｉＯ２系低膨胀玻璃在制备过程中常出现玻璃试样的开裂现象，本文以此为例，探讨了微晶玻璃强度的显微结构基础和制备过程中若干控制因素以保证强度的条件，提出了改善Ｌｉ２Ｏ－Ａｌ２Ｏ３－ＳｉＯ２系低膨胀微晶玻璃强度的可能途径。更多还原

【Abstract】 The mechanical strength of glass ceramic materials is important characteristics for evaluating the suitability of a given substance for a particular application.Taking the Li 2O Al 2O 3 SiO 2 low expansion coefficient glass ceramic for example,we discussed the microstructure and technical factors and proposed the possible method to impove the mechanical strength of this kind of glass ceramic materials.更多还原
