Beschreibung
Zusammenfassung:	This method for preparing a titanium and niobium mixed oxide comprises the following steps: -preparation of a titanium and niobium mixed oxide in amorphous form by solvothermal treatment of at least one titanium precursor and at least one niobium precursor; -mechanical crushing of the titanium and niobium mixed oxide obtained from the solvothermal treatment; -calcination of the mixed oxide obtained after crushing. Ce procédé de préparation d'un oxyde mixte de titane et de niobium comprend les étapes suivantes: -préparation d'un oxyde mixte de titane et de niobium sous forme amorphe par traitement solvothermal d'au moins un précurseur de titane et d'au moins un précurseur de niobium; -broyage mécanique de l'oxyde mixte de titane et de niobium obtenu à l'issue du traitement solvothermal; -calcination de l'oxyde mixte obtenu après broyage.
