摘要：

This paper describes the synthesis of some apatite compounds, called britholites, by an aerosol pyrolysis technique, which compared to conventional methods of solid-state chemistry, presents the advantages of reducing noticeably the temperature and the duration of the treatment. Britholites are minerals based on Ca(10-x)Ln(x)(PO4)(6-x)(SiO4)(x)X-2 formula (with X = F-, OH-, X-2 = O2-); they are promising materials for nuclear waste storage. In a second part we have synthesized and characterized a new apatite phase where the substitution of calcium by barium in britholite leads to a monophased solid solution Ca9-xBaxNd(PO4)(6-x)(SiO4)F-2 for 6 < x < 9. The possible interest of this new material is discussed. (C) 2001 Kluwer Academic Publishers.
