Abstrakt: Over the years, the conventional approach to producing bioglass involves the use of costly raw materials, such as silica and calcium carbonate. In order to ensure sustainability and reduce the consumption of these natural resources, the recent approaches have been tailored toward waste utilization. In this work, 45S5 bioglasses were prepared using rice husk ash (RHA) and chicken eggshell ash (CEGSA) as alternative materials at varying inclusions by microwave energy-assisted melt-quenching approach. The obtained bioglasses were characterized for their structure, mechanical, morphology, and bioactivity. The results showed all the developed bioglasses exhibited amorphous broad hump structure. The morphology showed irregular microstructure containing heterogeneous grains of rough and porous surfaces, respectively, essential for bone ingrowth and cell infiltration. At the same time, a sponge-like appearance of carbonate-hydroxyapatite was well pronounced on all the samples after immersion in simulated body fluid. The developed bioglasses also showed considerable mechanical properties with maximum hardness and compressive strength of 2.55 GPa and 64.5 MPa obtained for 45BGw50 sample. The bioglasses also showed good antibacterial properties to justify their use for biomedical applications.
