title: Preparation and chemical characterization of high purity fluorapatite.
abstract: High purity fluorapatite (FAP) was prepared by solid state reaction, in flowing argon gas, at 1370 degrees C for 60 min. For chemical characterization of Ca(10)(PO(4))(6)F(2), the accuracy and reproducibility of different analytical methods were assessed. Methods with a good accuracy for the determination of Ca, P and F content were: titrations with EDTA for Ca determination (accuracy: -0.8%), spectrophotometric method for P determination (accuracy: +0.6%) and measurements with fluoride-selective electrode (accuracy +5.4%) for F determination.
