Zangvil, Avigdor Pekin, Senol 2015-09-25T20:53:42Z 2015-09-25T20:53:42Z 10000-01-01 2000 2000 Sintering of gel-cast calcium hydroxyapatite was studied by means of thermal analysis, XRD, mechanical testing, and SEM, both for sub-micron and the agglomerated powder type. Transformation temperatures of tri-calcium phosphate upon cooling were determined as 1475°C for (alpha' to alpha, 1190°C for alpha to beta, and 800--700°C range for beta to hydroxy-oxyapatite transformation. Dilatometry revealed that dimensional change reaches to saturation at 1200°C. Mechanical testing of the parts sintered at 1200--1500°C revealed that compressive strength in the 2--10 MPa range was achieved. Made available in DSpace on 2015-09-25T20:53:42Z (GMT).
