✦ Synopsis

Although hydroxyapatite (HAP) is applied to medical im-tion of ͗210͘. The CHAP single crystals were broken in air, plants because of its biocompatibility, no data on mechanical water, and air after immersion in alpha minimum essential strength of HAP single crystals were yet available, partly medium (ͰMEM) ϩ 10% fetal bovine serum (FBS) for 3 due to the difficulty in obtaining sufficiently large single weeks. The average bending strength of the CHAP single crystals. In the present study the bending strength of OH-crystals was 468 Ϯ 205, 361 Ϯ 199 and 501 Ϯ 212 MPa in carbonated hydroxyapatite (CHAP) single crystals contain-air, water, and air after immersion in ͰMEM ϩ 10% FBS, ing carbonate of 0.09 CO 2 wt % prepared hydrothermally respectively. In all cases the maximum strength at each cryswas determined in three-point bending tests. The three-point tal thickness value decreased in inverse proportion to the thickness. ᭧ 1997 John Wiley & Sons, Inc. bending tests were performed using a modified ultra microhardness tester with a span of 380 Ȑm and a bending direc-
