摘要：

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(PO4)(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.
