Summary:A method for purifying lutetium includes providing a solid composition comprising ytterbium and lutetium and subliming or distilling ytterbium from the solid composition at a temperature of about 1196°C to about 3000°C to leave a lutetium composition comprising a higher weight percentage of lutetium than was present in the solid composition. L'invention concerne un procédé de purification de lutécium comprenant l'utilisation d'une composition solide contenant de l'ytterbium et du lutécium et la sublimation ou la distillation de l'ytterbium à partir de la composition solide à une température comprise entre environ 1196 °C et environ 3000 °C, afin d'obtenir une composition de lutécium présentant un pourcentage en poids supérieur de lutécium par rapport à celui présent dans la composition solide.
