• . In addition, the silica-containing cap-like structures exhibit a nanoscale composite architecture. They contain some amorphous silica and large proportions of the crystalline silica type α-cristobalite and are pervaded by a fine chitinous fibre network that very likely serves as a scaffold during the

Evidence for a crystalline structure of the siliceous teeth had already been mentioned earlier but unfortunately without showing and describing any results [30]. The recent analyses showed that the crystalline silica material present in the

Furthermore, a diffraction peak is located at approximately 22°, corresponding to the <101> of cristobalite, which indicates that crystalline silica phases are present in the diphasic gels during heating, while α-Al2O3 phases
