Crystallization effect on structural, mechanical and cytotoxic properties of bioglasses synthesized using conventional and biowaste as resources
43SiO2–25Na2O –7P2O5-(25-x) CaO -xMgO (x = 0, 5, 10, 15 (wt%)) glasses were synthesized using hybrid resources, i.e., biowastes and conventional chemicals. Non-isothermal crystallization kinetics of as-quenched glasses were investigated. The highest activation energy of crystallization (Ec) was observed for x = 15 wt% glass, i.e., 370 kJ mol−1. The as-prepared glasses were heat treated at (710–770 °C) for 1 h (h), 10 h, and 800 °C for 0.5 h to confirm the thermal results. The thermal expansion coefficient of glasses (∼10.4 × 10−6 °C-1) was decreased with MgO content and approached the range of human dentin and enamel. The MgO also hinders the crystallization in the present glasses. The M.T.T. assay test of glass and glass ceramics showed cell viability >80 % with a higher concentration of 200 μg/ml, even after 48 h on human peripheral blood mononuclear cells (P.B.M.C.). The biocompatibility of present glasses and glass ceramics was comparable to or even better than glass/glass ceramics synthesized using conventional chemicals. Utilizing these bioglasses and glass ceramics opens a pathway for hybrid sources to synthesize biomedical materials without hampering their bioactive properties.
