【Abstract】 Glass-ceramics is a high-technology and novel ceramic materials with homogeneous and dense microstructure and nano-or submicro-crystals, attained by in-situ crystallization in glass. For its excellent abrasion resistance,corrosion resistance and mechanical,thermal,electrical properties,glass-ceramics has been one of hot issues in research and application of novel ceramic materials.Fabrication technology of glass-ceramics including melting, sintering,sol-gel,strengthening and toughening was introduced,and its properties and applications were discussed.更多还原
