Abstract (EN):
This work reports the structure of two glass ceramics prepared in the calcium phosphate system, MK5B and MT13B, using (31)p MAS-NMR technique. The results obtained showed that the network of MK5B consisted mainly of Q(1) and Q(2) groups. Besides these two groups, MT13B material also present Q(3) units. The Q(n) groups detected in both glass ceramics seem to be correlated to the crystalline phases present in their microstructure.
