Preparation and characterisation of novel foamed porous glass-ceramics on the basis of bioglass 45S5.

This study determines the possibilities of synthesis of porous glass-ceramic materials based on Bioglass 45S5 using different methods obtained porous materials. In this work used foaming with sintering method for the set: bioglass 45S5 + glass cullet (CRT) + glass water (WG) and method sintering with forming-pore agents for the: bioglass + glass water (WG) + dried banana peels. The sets were melting and the next step sintering process. The resulting foams were examined and analysed for structural, microstructural, and physical properties. The research allowed for a quantitative and qualitative assessment of the foaming process generated by the presence of WG with the addition of CRT cullet and WG together with dried banana peel. It was found that WG with the addition of CRT cullet was a solution that offered the possibility of obtaining a large number of evenly distributed pores and higher total porosity compared the second set (WG + banana peel). Moreover, the use of CRT cullet and banana peel allowed the introduction of biogenic elements such as strontium, barium and potassium into the obtained materials, which have a positive effect on the stimulation of osteogenesis.
