Theory, Technology & Microstructure of Glass Ceramics " A powerfull Potential for New Products"

Glass-ceramics are so called heat treated glass(s) to produce a mixture of glassy and crystillne phases. These types of ceramics are generally produced via melting process and a controlled nucleation and growth. The nature of glassy phase, the type and amount of crystalline phases and their distribution are important parameter to control the final properties.The main goal this paper was to have a general review of glass ceramics as a big potential to produce new ceramics and their applications. Then, a few case studies are discussed, which were glass ceramics as a biomaterials and machinable and transparent glass ceramics. In this regards, the following equipment are applied; XRD; SEM; STA and spectroscopy.
