Fig. 1. Schematic illustration of dual-core-type granule preparation and primary characterization of the core–shell bioceramic granules. (A) Schematic procedure of bioceramic fiber precursor preparation (inset shows the outward appearance of granules after sintering treatment); (B) changes in diameter of the fibrous granules; (C) representative stress–strain curves for the granules; (D) XRD patterns of ion-doped CSi powders; (E) XRD pattern of β-TCP powders; (F) XRD pattern of har powders.
