| Popis: | One material that can be used in bone and soft tissue engineering is bioglass. By adhering to bone tissues and forming an apatite layer that further starts the biomineralization process, it can also encourage skin regeneration and wound healing in addition to playing a significant part in the healing processes of bone fractures.In this research, Syrian clay was used as a cheap silica source for preparation bioglass by melting method. Pure silica was isolated by mixing clay with sodium hydroxide in the following amounts (1:1), (2:1), (3:1), treated at different temperatures (700, 800, 900)˚C, treated with HCl solution, filtrated, dried, the yield reached to 96% with purity of 99% when clay was mixed with NaOH by (2:1) and treated at 800˚C. Bioglass was prepared using isolated silica according to thermal program, the formation of bioglass was confirmed by XRD, IR and biodegradability test, which confirmed formation of hydroxyapatite, on the surface which confirmed the biological effectiveness of the prepared bioglass. |
