Zirconia-containing wollastonite (CaSiO 3 ) ceramics with partial substitution of zirconia (1, 3 and 5 mol%) were prepared using eggshells and rice husk ash as source materials for calcium oxide and silica, respectively, through a sol–gel technique. The effect of incorporation of zirconia on in vitro bioactivity, mechanical properties, degradability and cytocompatibility of wollastonite was studied. Bioactivity was evaluated by in vitro assay using simulated body fluid while degradability was tested in Tris-HCl buffer solution for different time periods (1, 3, 7, 14 and 21 d) according to the ISO 10 993-14 standard. Human osteosarcoma (MG-63) cells were used to assess cytocompatibility with the MTT assay. X-ray diffractometry, Fourier transform infrared spectroscopy and scanning electron microscopy–energy dispersive spectroscopy were used to characterize the ceramics before and after in vitro studies. The results obtained showed that increasing the ...
