摘要: Abstract In this study, novel composites consisting of electrospun titanium dioxide (TiO 2 ) nanofibers incorporated into high-purity wollastonite glass ceramics were prepared as materials for use in hard tissue engineering applications. These characterized and investigated by means physical, mechanical vitro studies. The proposed composite showed greater densification better characteristics compared to pure wollastonite. influence temperature TiO content was investigated. Typically, /wollastonite having 0, 10, 20 30 wt% metal oxide sintered at 900, 1100 1250 °C. results indicated that increasing leads increase the bulk density, compressive strength microhardness with negligible, high moderate temperature, respectively. While porosity water adsorption capacity decreased a considerable impact sintering both properties. Moreover, bone-like apatite formed on surface wollastonite/TiO soaked simulated body fluid (SBF). All these show inclusion improved while preserving its bioactivity; hence, may be used bone substitute load bearing sites.
