Optimal Conditions for Aqueous Tape Casting of Hydroxyapatite

Article Preview

Abstract:

An aqueous tape casting process was employed to produce hydroxyapatite (HA) sheets. The effects of viscosity of slurry, blade height and speed on flexural strength and density of the sintered HA sheets were studied using central composite design (CCD). The flexural strength and the density were measured using a three-point bending test and Archimedes method, respectively. Results suggested that all parameters and the interaction between viscosity and speed had significant effects on both flexural strength and density. Under the conditions studied, the optimal conditions for the maximum flexural strength and density of the sintered HA sheet were obtained with the viscosity of 1532 mPa.s, the blade height of 3.34 mm and the speed of 6.27 mm/s.
