Physical and Mechanical Characterization of Crystalline Pure β-Tri Calcium Phosphate & Its Dopants as Bone Substitutes

Abstract

β-Tri calcium phosphate ceramics play a significant role in several biomedical application for their marked resorbability and bioactivity. One of them is in bone grafting, where it is used for treating bone defects caused by wounds or osteoporosis. In the present work an in-depth and systematic study of pure and different doped variants (Zinc, Magnesium and Titanium) of β-Tri calcium phosphate was done. We have prepared pure β-Tri calcium phosphate and its different dopants of different strength. All together seven different composition were studied. We have tried to investigate some important features which are the prerequisite for their application. These include lattice parameter study, mechanical properties, contacts behaviour with SBF, haemolytic characteristics, and its cytotoxic nature. The capability of new apatite development on the surface of pure and doped β-TCP samples were also considered and compared by using Simulated Body Fluid (SBF) to observe their interaction with human body fluid.
