Abstract

Ved å utgå fra kjente edelmetallnett av palladium og minst et annet edelmetall, blir det nå foreslått et gjenvinningsmetall, som er prisgunstig i fremstilling og det dannes mindre utskilte komponenter og dette er egnet både for anvendelse som gjenvinnings- nett og som katalysatomett. Oppfinnelsen angår et gullfritt edelmetallnett av palladitim og inneholder platina i en konsentrasjon i området fra 8 til 25 vekt-%.By starting from known precious metal networks of palladium and at least one other precious metal, a recycled metal is now proposed, which is economical in manufacture and less separated components are formed and this is suitable both for use as a recycling network and as a catalyst network. The invention relates to a gold-free precious metal network of palladium and contains platinum at a concentration in the range of from 8 to 25% by weight.
