以CaO-Al2O3-SiO2-10%MgO系相图为理论依据,采用熔融工艺制备辉石微晶玻璃。运用差热分析（DTA）、X射线衍射仪（XRD）、电子探针分析（EPMA）、能谱仪（EDS）、显微硬度等测试手段,研究了微晶玻璃的玻璃基体、晶相组成。结果表明810℃保温1 h、再以10℃/min的升温速率升至960℃保温1 h的热处理工艺,获得了以单一辉石Mg0.89Fe0.08Al0.20Cr0.04Ti0.01Ca0.76Na0.10Si1.92O6为晶相的微晶玻璃;基体玻璃中原子种类十分复杂,既有网络形成体,又有网络修饰体和网络中间体,由于[SiO4]四面体中Si-O（桥氧）键太少,玻璃网络断裂严重,该基体玻璃容易析晶。
Pyroxene glass-ceramics were prepared by melting method on the basis of CaO-Al2O3-SiO2-10% MgO phase diagram.Crystalline phase and glass matrix of the glass-ceramics were investigated by means of differential thermal analysis（DTA）,X-ray diffraction（XRD）,electron microprobe analysis（EPMA）,energy dispersive spectrometer（EDS） and microhardness test.The results show that pyroxene glass-ceramics with single-crystal of Mg.89Fe.08Al.20Cr.04Ti.01Ca.76Na.10Si1.92O6 can be obtained in the sample heated at 810 ℃ for 1 h and subsequently heated to 960 ℃ holding 1 h with the heating rate of 10 ℃/min.The atoms in glass matrix is very complicated,not only including the network former,but also the modified cation and the intermediate former.Because of too little Si-O（bridging oxygen） in the ,disconnection of the glass network is serious,the matrix glass is easy of crystallization.
