2. Characteristics and properties of nanocrystalline apatites

2.1 Physico-chemical characteristics

Stoichiometric hydroxyapatite (HAP) differs from the apatitic phase of bone mineral or dentin in a number of ways. Bone or dentin apatite has a low degree of crystallinity due to the nanometric dimensions of its constituent crystals, as well as a crystalline disorder essentially linked to the sub-stoichiometry . The non-stoichiometric character is determined by...
