Abstract

PARA FABRICAR UNA PIEZA CONFORMADA DE UN MATERIAL DE CONTACTO BASADO EN PLATA, EN ESTA INVENCION SE HA PREVISTO FORMAR UNA MEZCLA DE PLATA Y DE UN OXIDO METALICO, QUE SE TRATA EN UN PROCESO PULVIMETALURGICO HASTA OBTENER LA PIEZA CONFORMADA, Y EN EL QUE EL OXIDO METALICO SE REDUCE A METAL. COMO HAY DISPONIBLE POLVO DE OXIDO METALICO DE GRANO MUCHO MAS FINO QUE EL DE POLVO METALICO, PUEDE CONSEGUIRSE UN MATERIAL DE CONTACTO CON UN TAMAÑO MEDIO DEL GRANO METALICO QUE INTERVIENE COMO COMPONENTE ACTIVO MENOR QUE 1 MI M. ESTA GRANULACION FINA CONFIERE A ESTOS MATERIALES DE CONTACTO UNAS PROPIEDADES ESPECIALMENTE FAVORABLES PARA LA CONMUTACION.
