Phosphate glass-ceramics

In Germany, a silica-phosphate glass-ceramic has been developed and used clinically. It consists of fluorhydroxyapatite (Caio(P04)e(OH,F)2) and phlogopite ((Na,K)Mg3(AISi30io)F2), a type of mica [88,94-96],...

In addition to apatite and the AlPO -modifications, phosphates of the nasicon-type structure are also important in silica-free phosphate glass-ceramics. Winand et al. (1990), have shown that Na IiCPOj) belongs to the nasicon-type structure of Naj Zr2P3 j Si 0 2- The space group is Rdc. Divalent ions may also be inserted into these structures without changing the nasicon structure. According to Schulz et al. (1994), the complex structural formula can be written as follows ... 

Since phosphate glass-ceramics exhibit some properties that are more favorable and others that are less favorable than those of silicate glass-ceramics, their special characteristics should be addressed at the beginning of this section. Most of these features are attributed to the different nucleation and crystallization conditions of phosphate glass-ceramics compared with those of silicate glass-ceramics. The glass structure provides the basis for these characteristics. Therefore, the structures of the two glass-ceramics fiunilies must be addressed. 

Rogier and Pernot (1991) also succeeded in developing composites of phosphate glass-ceramics and titanium, and composites of phosphate glass-ceramics and stainless steel (Pernot and Rogier, 1993).
