Abstract
The interface bonding of α-tricalcium phosphate (αT) porous ceramic couple in H2O and SBF was investigated. The bonding occurred with the entanglements of HAp microcrystals formed in the interface narrow space between αT ceramic couple. The HAp had calcium-deficient compositions with HPO42- and/or CO32-. The HAp formation extent was in the order, open free surface « interface narrow space, which was assumed to depend on how ease the supersaturated solution conditions with respect to HAp was realized.
