Sol-Gel Fabrication of Glass-Ceramic Composite Materials for Dental Application

The role of calcium (source & content) on the in vitro behaviour of sol–gel quaternary glass series

“…The sharp peak observed at 1385 cm −1 in Fig. 4 can be attributed to the NO 3 − group [33]. Its intensity is higher in the case of A−glasses.…”

“…The band at 1460 cm -1 in N−glasses, and its two separate peaks at 1490 and 1420 cm -1 , can be assigned to amorphous calcite [31,32]. The sharp peak at around 1385 cm −1 , attributed to the NO 3 − group [33], appears with a higher intensity in the case of A−glasses.…”

Sol-gel as methodology to obtain bioactive materials

“…The sol-gel process is attractive because it uses mild conditions and easily available precursors. Countless literature works have reported the use of this route to prepare calcium-based compounds with applications in biomaterials (Radev et al 2012, Wei et al 2011, Heinemann et al 2011, Jadalannagari et al 2011, Bandeira et al 2011, Chatzistavrou et al 2011, Arcos and Vallet-Regí 2010.…”
