Abstract

This work reports the structure of two glass ceramics prepared in the calcium phosphate system, MK5B and MT13B, using ³¹P MAS-NMR technique. The results obtained showed that the network of MK5B consisted mainly of Q¹ and Q² groups. Besides these two groups, MT13B material also present Q₃ units. The Qⁿ groups detected in both glass ceramics seem to be correlated to the crystalline phases present in their microstructure.
