Claims19
A permanently polarized hydroxyapatite, characterized in that its crystallinity is over 65% and its corresponding NMR 31P spectrum shows a unique peak at about 2.6 ppm corresponding to phosphate groups of hydroxyapatite, wherein said spectrum is carried out with solid hydroxyapatite using H3PO4 as a reference, and said permanently polarized hydroxyapatite has a surface capacitance which decreases less than 8% after 3 months.
