ADVANTAGES OF GLASS-CERAMIC FORMATION

All these different ways of forming microstructures involve controlled nucleation and crystallization, as well as the choice of parent glass composition. 

Glass-ceramics demonstrating particularly favorable properties were developed on the basis of these two key advantages, that is, the variation of the chemical composition and of the microstructure. These properties are listed in Tables 1-1 and 1-2, and are briefly outlined below  

Particularly Favorable Properties of Glass-Ceramics Processing properties 

Rolling, casting, pressing, spin casting, press-and-blow method, drawing are possible 

Limited and controllable shrinkage No porosity in monolithic glass-ceramics
