A dental-filling material with hardnesses exceeding 100 HV for gold-condensation is prepared from a gold-alloy powder of which the alloying components are metals resulting in hardening gold alloys and which are simultaneously soluble in nitric acid. A rough, pure gold layer on the surface of the powder particles is obtained by treatment with nitric acid.
