The most important glass-ceramic compositions are probably based on lithium silicates. The phase diagram of the Li20-Si02 system is shown in Fig. 9.16. The commercial compositions usually contain more than about 30 percent lithia which upon crystallization yields Li2Si205 as the major phase with some Si02 and Li2Si03.

In summary, phase diagrams can determine the feasibility of coexistence of crystal species in glass-ceramics. They cannot, however, yield any information regarding such issues as nucleation, grain growth, or other kinetic phenomena.
