Synthesis of hydroxyapatite from eggshell powders

2016-3-1 · Subsequently, the hand-ground eggshell powder and DCPD were homogeneously mixed with deionized water in a zirconia container. The ratio of eggshell powders to DCPD was 4:3 (mole ratio). The resulting mixture was wet-milled in a planetary ball-milling machine (QM-3SP4J, Nangjing, China) for 1, 5, or 10 h at a speed of 170 rpm in a zirconia bottle.
