The composites were synthesized using two concentrations (25/75 wt% and 50/50 wt% - bioactive glass/hydroxyapatite) and two sintering temperatures (530 and 1000 °C).

Herein, we summarized the recent advances in the synthesis approaches of microwave absorption materials. Then, based on EMW absorption theory, the microwave absorption of pure and biocarbon-based composite absorbers has been discussed in detail. Since biocarbon keeps its natural morphology after carbonization we classified the biocarbon-based absorbers into three categories: 1) 1D microstructures, 2) 2D flaky microstructures, and 3) 3D porous microstructures. In addition, the effect of surface modifications and doping of these microstructures with different dielectric/magnetic compounds have been analyzed. By comparative analysis of reported literature on these microstructures, 3D porous biocarbon microstructures and their composites emerge as the most promising candidates as low-cost and efficient EMW absorbers.
