Das vorliegende Verfahren zum Herstellen eines keramischen Pulvers zum Pulverbeschichten einer Komponente einer Hochtemperatur-Brennstoffzelle umfaßt zwei Schritte. In einem ersten Schritt wird eine Lösung aus wenigstens einem Salz wenigstens eines Metalles und aus einem organischen Komplexbildner thermisch zu einem porösen keramischen Werkstoff zersetzt. Der poröse keramische Werkstoff wird in einem zweiten Schritt zu einem keramischen Pulver pulverisiert. Production of a ceramic powder (18), comprises: (a) thermally decomposing a solution of a metal salt and an organic complex former, to a porous ceramic material (14); and (b) pulverising the porous ceramic material (14).
