Obtaining of strontium doped fluorapatite powders


NSC "Kharkiv Institute of Physics and Technology", Akademicheskaya 1 Str., 61108 Kharkiv, Ukraine


Possibility of obtaining powders of calcium Ca10(PO4)6F2 and strontium-containing Ca9Sr(PO4)6F2 fluorapatites by both solid phase reaction method with subsequent heat treatment and chemical co-precipitation method from solutions of the initial components was investigated. It was shown that the total synthesis of calcium Ca10(PO4)6F2 and strontium-containing Ca9Sr(PO4)6F2 fluorapatites by solid phase method occurs at a temperature of 900 °C, and by chemical co-precipitation as a result of the reaction between initial components. Obtained nanosized powders of calcium and strontium-containing fluorapatites were produced by chemical co-precipitation method.
