Ternary
diagrams (wt %) for (A) CS–HAP and (B) HA–HAP
colloidal mixtures identifying overlay of desirable regions of rheological
yield (dotted line), shear-response (dashed line), and swelling properties
(dot-dashed line). Images of extruded mixtures (via 21-gauge needle)
of (C) pure CS (15%), (D) CS–HAP (15–60%), (E) pure
HAP (60%), (F) HA–HAP (15–60%), and (G) pure HA (15%)
(w/v).
