Preparation and characterization of novel bioactive dicalcium silicate ceramics

3D printed porous β-Ca2SiO4scaffolds derived from preceramic resin and their physicochemical and biological properties

“…Previous studies confirmed the good cytocompatibility for β-Ca 2 SiO 4 materials [18,21,22]. Our study demonstrated that β-Ca 2 SiO 4 scaffolds derived from preceramic polymer and CaCO 3 active filler were able for cell adhesion, proliferation, and differentiation.…”

“…Ca 2+ ions in β-Ca 2 SiO 4 interact with H 3 O + ions in SBF, which could promote the formation of rich-Si layer on the ceramics. The rich-Si layer induces the formation of Ca–P nucleation and further apatite crystal formation [21,53]. In this study, the Ca/P ratios were 2.29, 2.41, and 2.50 for the scaffolds sintered at 1000 °C, 1100 °C, and 1200 °C, respectively, which are a little higher than that of 1.67 for apatite.…”

“…Dai et al [18] prepared porous β-Ca 2 SiO 4 by sol–gel method, which showed good mineralization ability and cytocompatibility. Gou et al [21–23] reported that β-Ca 2 SiO 4 had a moderate degradation, and the dissolved ions could enhance the proliferative response of fibroblasts.…”

Characterization of the Firing Steps and Phases Formed in Mg-Zr-Containing Refractory Dolomitic Materials

“…However, regarding Zr-O vibrations belonging to zirconia, these frequencies are observed at 574 and 490 cm -1 , in the spectra of samples treated below to 1350ºC. The absorptions located between 910-880 cm -1 and at 980 cm -1 , are attributed to Si-O symmetric and asymmetric stretching, respectively; which are the typical vibrational modes of the silicate moieties forming the structure of the phase β-C 2 S (Gou et al, 2005). These bands are observed, in samples submitted to calcination over 1000ºC, and subsequently its definition improves, as a consequence of bond reinforcing with the temperature increases.…”

Design and characterization of bioceramic coating materials for Ti6Al4V

“…5. It can be seen that the reflectance at the wavenumbers of 568 and 602 cm -1 [9,10] corresponding to P-O have become intensive after the immersion in SBF. They served as indication of an increase in apatite phase.…”
