摘要：
In this present study, hydroxyapatite which was obtained from cattle bones has been heat treated at temperature 400 degrees C and 600 degrees C. The microstructure after the treatment has been studied in detail using Transmission electron microscopy (TEM) and X-ray diffraction techniques. The TEM results indicate that natural bone consists of collagen and hydroxyapatite nano-crystals which are needle shaped. The heat treatment influences the crystallinity and growth of these hydroxyapatite nano-crystals known as 'crystal maturation' or 'crystal ageing'. (C) 2015 Elsevier Inc. All rights reserved.
