Abstract

26 ABSTRACT There is provided a method for producing fluorapatite crystals, the method comprising the steps of: a) providing a first aqueous solution comprising a phosphate source and a fluoride source, said first aqueous solution being supersaturated with respect to the5 phosphate source and the fluoride source, b) providing a second aqueous solution comprising a calcium source, said second aqueous solution being unsaturated with respect to the calcium source, c) mixing the first aqueous solution and the second aqueous solution thereby providing a mixture comprising fluorapatite crystals and a further aqueous10 solution, d) optionally stirring the mixture of step c), e) optionally heating the mixture of step c) and/or step d), f) separating the fluorapatite crystals from the further aqueous solution, g) optionally drying the fluoroapatite crystals of step f), and 15 h) optionally milling the fluorapatite crystals obtained in step f) or step g).
