WebOct 1, 2024 · The dielectric and electrical conduction studies of hydroxyapatite compound was done over a wide range of frequency (102 – 105 Hz) and temperature (500 C – 5000 C) respectively. Hydroxyapatite, also called hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but it is usually written Ca10(PO4)6(OH)2 to denote that the crystal unit cell comprises two entities. Hydroxyapatite is the hydroxyl endmember of the complex apatite group. The OH ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or ch…
