Hydroxyapatite whiskers (w-HA) were synthesized by a hydrothermal method in order to develop HA whisker electrets for biomedical utilization. Whiskers synthesized via ACP were proved to be Ca-deficient HA with a Ca/P molar ratio of 1.53. The HPO42- in the Ca-deficient whiskers was responsible for the high ionic conductivity in the temperature range of 250 - 600ºC.
