Glass ceramics can be considered as a composite material containing both glassy and crystalline phases, and exhibit various excellent properties. In the past decades, the nucleation and crystallization processes in glass have been investigated, and possible applications of glass ceramics have been discussedextensively. However, the applications of glass ceramics are still very limited due to lack of useful and efficient manufacturing techniques. We are aiming to develop some techniques which can realize efficient preparation of glass ceramics for various applications. In this talk, we will introduce 3D printing and injection molding technique for glass-ceramic color converter, melt in tube technique for fabrication of glass ceramic optical fibers with both low attenuation and good broad band optical amplification property, and space-selective control of precipitation of nanocrystals in glass by using fs laser. Their physical mechanisms have been discussed and promising applications have also been demonstrated.
