Determination of Crystal Phases

Therefore, the faster growth of lithium disilicate is a result of a solid-state reaction between lithium metasilicate and cristobalite (Section 2,1.1). 

Identification of crystal phases in glass-ceramics can also be made through solid-state nuclear magnetic resonance (NMR) 

Rgure 3-23 High-temperature X-ray diffraction, HT-XRD, of a multicomponent glass-ceramic of lithium disilicate type. A = Li SiOg, B = U2Si205, C = Si02 (cristobalite), and D = U3PO4.
