Influence of design on bioactivity of novel CaSiO3–CaMg(SiO3)2 bioceramics: In vitro simulated body fluid test and thermodynamic simulation

New evaluation of the in vitro response of silicocarnotite monophasic material

“…The study of the first stages of the reaction process of C5SP in SBF in the present work evidences experimentally and reinforces the mechanism proposed in the literature to explain the bioactive response of calcium silicate/phosphate biomaterials. On the other hand, the reaction of silicocarnotite in SBF described here is in good agreement with the mechanism proposed to explain the bioactivity of calcium silicophosphate glasses [3,4,28,42].…”

“…Keeping in mind the mechanism process proposed by several authors [3,4,9,28,42], to explain the bioactive response of calcium silicate/phosphate materials and the experimental result obtained in the present work, the reaction of silicocarnotite in SBF can be described as a dissolution-precipitation process. The X-ray diffraction and EDS results revealed the preferential dissolution process of the silicocarnotite while the precipitation of new phases on the material surface was evidenced by FE-SEM and AFM microscopy.…”

Influence of needle-like morphology on the bioactivity of nanocrystalline wollastonite – an in vitro study

“…Wollastonite is expected to induce osteogenesis by satisfying all these criteria, hence it can be used as an artificial bone implant material. 19,20 The various synthetic methods employed for the preparation of wollastonite are solid-state, 21 hydrothermal, 22 coprecipitation, 23 and solution combustion synthesis. 24 The most widely used method for the preparation of wollastonite is the sol-gel method, as the synthesized particles are homogeneous and the particles were found to be in the nano-regime.…”

The crystallization behaviour and bioactivity of wollastonite glass-ceramic based on Na2O–K2O–CaO–SiO2–F glass system

“…This fact suggests the possibility of extraction of calcium ions, from the wollastonite structure, by protons from the SBF and therefore facilitates the precipitation and formation of the HA layer on the surface of the material. Sainz et al [32] demonstrate that the pseudo-wollastonite is significantly more soluble in SBF than low temperature wollastonite form CaSiO 3 . Pseudo-wollastonite contains needle-like structures with significant Ca and Si ions content that favours the formation of an apatite layer on the surface of the wollastonite sample [33].…”
