Development of Bioactive Alumina-Wollastonite Composite by Electrophoretic Deposition

Abstract:

Alumina is excellent biomaterial and used in hip prostheses, dental implants and so on. Wollastonite particles were deposited in pores of porous alumina by electrophoretic deposition and an alumina-wollastonite composite was produced. Apatite was formed both inside the pores and on the surface of the composite of the alumina-wollastonite composite by soaking in a simulated body fluid. It was indicated that the deposited wollastonite particles induced the apatite formation. Novel composite material with both excellent mechanical properties and high bioactivity was developed.
