Notes:
Sol–gel synthesis is used for the fabrication of new materials with technologicalapplications including ceramics for implants manufacturing, usually termed bioceramics. Manybioactive and resorbable bioceramics, that is, calcium phosphates, glasses and glass–ceramics, havebeen improved by using the sol–gel synthesis. In addition, the soft thermal conditions of sol–gelmethods made possible to synthesize more reactive materials than those synthesized by traditionalmethods. Moreover, new families of bioactive materials such as organic–inorganic hybrids andinorganic compounds with ordered mesostructure can be produced. In hybrid materials, theinorganic component ensures the bioactive response whereas the organic polymeric componentallows modulating other properties of the resulting biomaterial such as mechanical properties,degradation, etc. On the other hand, the sol–gel processes also allow the synthesis of silica orderedmesoporous materials, which are bioactive and exhibit – as an added value – a possible applicationas matrices for the controlled release of biologically active molecules (drugs, peptides, hormones,etc.). Finally, by combining the bioactive glasses composition with synthesis strategies ofmesoporous materials, template glasses with ordered mesoporosity can be obtained. In this chapter,the advances that sol–gel technology has brought to the silica-based bioactive bioceramics arepresented
