Article Preview

Two kinds of dense calcium phosphate (Ca-P) bioceramics, hydroxyapatite (HA) and β- tricalcium phoshpate/hydroxyapatite (β-TCP/HA), sintered by microwave plasma were investigated. The dense HA and β-TCP/HA bioceramics exhibited higher density, smaller grain size and higher Vickers hardness. The sintering behaviors of HA powder were also significantly different from those of calciumdeficient hydroxyapatite (d-HA) powder by the same microwave plasma sintering route. The sintering efficiency of the former was higher than that of the latter. The results indicate that dense HA and β-TCP/HA bioceramics are of better mechanical strength and might have better bioactivity.
