dc.description.abstractNa2SiO3 solution and chloride solutions of calcium and magnesium were used as raw materials. HCl was added to Na2SiO3 solution resulting in gel of silica. In order to obtain a mixture of Si gel, Ca2+ and Mg2+, calcium and magnesium solutions were blended into the gel. After adding NaOH to the mixture, Ca2+ and Mg2+ ions precipitated as hydroxides. Subsequently, it was dried to attain the ceramic precursor powder, which was calcined at 900 ºC for 1h, compacted into a pellet form and sintered at 1200 ºC for 2h. The ceramic body was characterized by SEM, XRD and FTIR. In vitro test for bioactivity verification was performed in SBF. A surface deposition of hydroxyapatite on the ceramic body was observed after 3 days. The cytotoxicity test revealed that the material has cell viability above 70%, meaning that it is not toxic for the cells, according to ISO 10993-5 standard.pt_BR
