Abstract
Electrovectorial effect for ambient calcium ion of polarized ceramics surfaces was investigated. The concentration distribution of the calcium ion in SBF was observed using a confocal laser scanning microscope (CLSM). The polarized HAp ceramic and the HAp ceramics were placed the N-surface opposite to P-surface or 0-surface and the P-usrface opposite to 0-surface vertically on a glass base dish. The CLSM indicated that the concentration distribution of calcium ion was higher near N-surface while that was lower near P-surface. The result of this examination proofed that N-surface attracted calcium ion whereas P-surface and calcium ion repulsed each othe rby electrovectorial effect.
