When the cements were mixed with 20 wt% NaH_2PO_4 solution at a powder-liquid ratio of 1.8 (powder g/liquid ml) and their pastes were stored in distilled water at 37°C for one week, apatite phase was identified in every cement. The of crystal shape was flake like and the size become smaller with an in crease in the TeCP content in the cement. When 20 wt% DL-malic acid solution was used as a liquid, the crystallinity of apatite was lower and non-reacteed particles remained to an appreciable extent. When 20 wt% NaH_2PO_4 and 20 wt% DL-malic acid solution was used as a liquid, the apatite phase detected in the cements showed an crystilled between those of the above two cements. No non-reacted particles were detected after one week immersion in distilled water for these cements. Our results suggested that the crystallinity and quantity of apatite could be controlled by changing the composition of solution, and hence this cement was applicable to a wide field as a bioactive
