Abstract

This report gives a new synthetic method of bioactive yttria-stabilized zirconia (YSZ) ceramics according to the so-called Vector Materials Science (VMS). Although YSZ ceramics have long been clinically used on account of the in vivo bioinertness, a small addition of hydroxyapatite (HA) successfully transformed YSZ to a bioactive material. The transformation was given an explanation by VMS; the resultant tri-calcium phosphate from the chemical reaction during sintering between YSZ and HA was found to induce SBF-active property to YSZ.
