FIELD: inorganic synthesis.
SUBSTANCE: invention relates to rare-earth metal chemistry, in particular to scandium chemistry. Preparation of K5Sc3F14 comprises interaction of 0.6 M scandium salt solution with potassium hydrodifluoride at F/Sc molar ratio at least 10. Resulting precipitate is separated from solution by filtration, washed with 1% potassium hydrodifluoride solution, dried and calcined at 300°C until constant weight is achieved.
EFFECT: simplified synthesis due to excluded co-melting operation.
