Effect of Process Variables on the Microstructure of Hollow Hydroxyapatite Microspheres Prepared by a Glass Conversion Method
{{output}}
Solid microspheres (diameter = 106-150 μm) of a Li(2)O-CaO-B(2)O(3) glass were reacted in a K(2)HPO(4) solution to form hollow hydroxyapatite (HA) microspheres. The effect of the temperature (25°-60°C), K(2)HPO(4) concentration (0.01-0.25M), and pH (9-12) o... ...
