Stability Compare between Hydroxyapatite and Calcium Carbonate Based on Experiment——Why Vertebrates Chosen Hydroxyapatite as Their Bone and Tooth Inorganic Material

Xin‐Yuan Sun

Abstract

Through evolution,vertebrates have chosen the calcium phosphate mineral apatite to mineralize their teeth and bones.We based on the basic principles of biomineralization and added different reagents to the solution which contain Ca2+ or Ca2+-PO3-4.The products to appear different morphologies with changes in different reagents,and they were characterized by scanning electron microscopy(SEM) and powder X-ray diffraction(XRD) analysis.We discussed the reason why vertebrates utilize the calcium phosphate mineral apatite for structural support.
