Preparation and in vitro bioactivity of CaSiO3 powders

Electrophoretic deposition of hydroxyapatite–CaSiO3–chitosan composite coatings

“…Similar to natural bone, the second layer contained HA nanoparticles in the organic matrix. It is expected that the deposition of the CS surface layer containing bioactive CS particles can promote osteointegration owing to the high bioactivity of this material [23][24][25]. The use of chitosan enables the cathodic EPD of layers of different materials and provides good interfacial bonding of the layers.…”

“…CS was reported to have a high bioactivity due to the fast formation of an apatite layer on its surface after soaking in simulated body fluid solutions [23][24][25]. It is known that the silanol groups on the silicate surface can provide favorable sites for apatite nucleation [26,27].…”

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.…”

Characterization of wollastonite coatings prepared by sol–gel on Ti substrate

“…There is a small peak at about 850°C which may be attributed to the glass transformation temperature and the exothermic peak at about 985°C which is due to the formation and growth of crystalline phases. 15 There is little weight loss when temperature is higher than 850°C. From the DSC curve of dried gel, we can see that the glass transformation temperature is about 850°C.…”
