Abstract

LA INVENCION SE REFIERE A UN MATERIAL PARA CONTACTO ELECTRICO BASADO EN OXIDO DE ESTAÑO-PLATA QUE CONTIENEN ZONAS DE OXIDO DE ESTAÑO Y ADEMAS OXIDOS Y/O CARBUROS EN UNA MATRIZ DE PLATA O EN UNA ALEACION QUE CONSISTE PRINCIPALMENTE EN PLATA. LOS OXIDOS Y CARBUROS ADICIONALES ESTAN CONTENIDOS EN LAS ZONAS DE OXIDO DE ESTAÑO Y/O EN UNA REGION DE TRANSICION ENTRE ELLAS Y LA MATRIZ DE PLATA. LA PROPORCION DE LOS OXIDOS ADICIONALES Y CARBUROS ALCANZA CONJUNTAMENTE HASTA 40 % EN PESO EN RELACION A LA CANTIDAD DE OXIDO DE ESTAÑO; LOS OXIDOS Y CARBUROS ADICIONALES PUEDEN SER AQUELLOS DE MOLIBDENO, TUNGSTENO, BISMUTO, ANTIMONIO, GERMANIO, VANADIO, COBRE O INDIO Y, APARTE DE UN COMPONENTE SOLUBLE QUE PUEDE SUCEDER, LA MATRIZ DE PLATA ESTA LIBRE DE OTROS OXIDOS Y CARBUROS.
