Abstract:

In this study, porous artificial bone from hydroxyapatite was fabricated usind garbonyl diamide space fille. In porous bioceramics applications has low mechanical properties, therefore new developments are required on production of porous ceramics. İn this study, calcium-phosphate in hydroxyapatite from (Nanotech Co. in Eskişehir) and carbonyl diamide balls in 50% rati were used to prepare the powder. To optimize the fabrication, sintering temperatures (950 ℃, 1050 ℃, 1150 ℃) and time (1-5h) wereoptimse to enhance the mechnical properties of porou ceramics. Afte sintering, pore size and microstructure of the samples were analyzed with scanning microsopy. Porous samples  were tested with compression test. From the results compressive strenght were changged between 1.2 MPa to 11 MPa depends on the process parameters. Keyword- artificial bone, hydroxyapatite, sintering, porous, comprerssion
