Acceleration and Deceleration of Bone-Like Crystal Growth on Ceramic Hydroxyapatite by Electric Poling

Abstract

Bone-like crystals were acceleratingly grown in a simulated body fluid on the negatively charged surface of electrically poled hydroxyapatite ceramics, while the crystal growth was completely inhibited on the opposite surface. The poling effect was generalized by the enhanced crystal growth on the poled ferroelectric ceramics of BaTiO3 and CaTiO3.
