Preparation of Dense Biphasic Calcium Phosphate Ceramics Using Eggshell Derived Nanopowders I.
Mohamad Department of Manufacturing and Materials Engineering, Faculty of Engineering, International Islamic University Malaysia, PO Box 10, 50728 Kuala Lumpur, Malaysia sopyan@iium.edu.my Keywords: Biphasic Calcium Phosphate, Dense, Eggshell, Mechanical, Physical, Characterization Abstract.
Dense calcium phosphate ceramics has been traditionally fabricated by sintering HA powders at high temperature via a uniaxial pressing, where samples lose uniformity and develop cracks once it is sintered [5].
In a nutshell, sintering temperature and compaction pressure gives the sintering condition which determines mechanical strength of dense BCP ceramics.
