| Abstract: | Beta-tricalcium phosphate based composites containing particles of barium hexaferrite were fabricated. The beta-tricalcium phosphate fine powder was synthesized from egg shell and Ca2P2O7 by a solid-state reaction technique. Effects of barium hexaferrite additive (0–3 vol%) on the properties of the composites were investigated. All samples showed a main phase of β-tricalcium phosphate, characterized by X-ray diffraction technique. The additive inhibited grain growth, but enhanced hardness of the composites. M–H hysteresis loops also showed an improvement in the magnetic behavior for higher barium hexaferrite content samples. However, in vitro bioactivity test indicated that the 2 vol% sample may be suitable for biological applications. |
