本文介绍了一种新的大颗粒透明微晶玻璃，它是通过从均匀玻璃中生长晶体的方法获得的，在晶化过程中玻璃基质和晶相组成的同步变化导致了这种大颗粒、高晶化体积的微晶玻璃的高透明性，这种微晶玻璃各相之间具有合适的折射率。研究了这种微晶玻璃的形核和晶化行为。利用差示扫描量热仪、X射线衍射仪和扫描电子显微镜确定了玻璃的最佳热处理制度。通过掺杂过渡金属或稀土元素，可以进一步改善这种新型微晶玻璃的光学性能，如激光特性等。
In this article we present a new kind of large grain transparent glass-ceramics obtained by the method of crystal growth from a homogenous glass, the simultaneous variation of the glass matrix and crystalline compositions during the crystallization results in the high transparency of this kind of large grain, high crystalline volume glass-ceramics, which have suitable refractive indexes between respective phases. The nucleation and crystallization behaviors of this kind of glass-ceramics have been investigated. The optimum heat treatment schedule for the glass was determined by means of DSC, XRD and SEM. The desirable optical property, such as laser characteristics etc, of this new kind of glass-ceramics can be further developed by doping with transition metals or rare-earths.
