摘要: Abstract Aqueous sol–gel chemistry route based on ammonium–hydrogen phosphate as the phosphorus precursor, calcium acetate monohydrate source of ions, and 1,2-ethylendiaminetetraacetic acid (EDTA), or 1,2-diaminocyclohexanetetracetic (DCTA), tartaric (TA), ethylene glycol (EG), glycerol (GL) complexing agents have been used to prepare hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 , CHAp). The phase transformations, composition, structural changes in polycrystalline samples were studied by infrared spectroscopy (FTIR), X-ray powder diffraction analysis (XRD), scanning electron microscopy (SEM). local short-range (nano- mezo-) scale effects CHAp using solid-state NMR spectroscopy. spatial 3D data from SEM images obtained TA, EG GL routes recovered for first time our knowledge.
