Crystallization of anatase from amorphous titania in hot water and in vitro biomineralization

Abstract

Anatase of good crystallinity has been developed on titanium substrates by soaking in a 30 mass% hydrogen peroxide solution at 80°C for 8 h, soaking in distilled water at ambient temperature for 12 h, and subsequently aging in distilled water at 80°C for 3d. The anatase layers exhibit good bioactivity as inducing apatite deposition in Kokubo's simulated body fluid within 2d.
