In order to be able to achieve a fine-grained separation without the formation of agglomerates to obtain a dental alloy with high mechanical stability and excellent polishing characteristics, it is proposed that the dental alloy contain - in addition to ruthenium as grain-growth inhibitor - at least one element of the group comprising tantalum, niobium, yttrium, zirconium, chromium, molybdenum as grain-refinement control element, whereby the dental alloy consists of (in % by weight): 0.03 to 1 ruthenium 0.03 to 2 grain-refinement control element 0 to 10 tin 0 to 10 zinc 0 to 10 indium 0 to 10 copper 0 to I gallium 0 to 10 platinum 0 to 2 iridium 0 to 2 rhodium 0 to 2 germanium 0 to 2 aluminium 0 to 2 silicon 0 to 2 cerium 0 to 2 lanthanum 0 to 2 iron, with the remainder being gold, palladium, and silver, whereby the sum of elements adds up to 100% by weight. 14
