Effect of ZrO 2 , TiO 2 , and Al 2 O 3 Additions on Process and Kinetics of Bonelike Apatite Formation on Sintered Natural Hydroxyapatite Surfaces
Source abstract
Abstract
In this study, the ability to form bone‐like apatite on surface of both pure natural hydroxapatite ( N ‐ HA ) and natural hydroxyapatite containing 5 wt% of ZrO 2 or TiO 2 or Al 2 O 3 , sintered at 1300°C for 2 h and soaked in the simulated body fluid for different times, was studied. It has been found that the presence of β‐tricalcium phosphate in N ‐ HA + 5 wt% ZrO 2 or TiO 2 has promoted the precipitation of bone‐like apatite in the Zr or Ti poorest regions. By contrast, the presence of 5 wt% of Al 2 O 3 did not induce any apatite precipitation on N ‐ HA sample surfaces.
