Abstract

LA INVENCION SE REFIERE A MATERIALES DE CONTACTO CON LA COMPOSICION AGSNO2BI2O3CUO QUE HAN PROBADO SU VALOR, EN ESPECIAL PARA DISPOSITIVOS DE CONMUTACION DE BAJO VOLTAJE. PUEDEN SER AÑADIDOS OTROS OXIDOS METALICOS A ESTOS MATERIALES. JUNTAMENTE A LA VIDA UTIL REQUERIDA Y A UN COMPORTAMIENTO DE SOBRETEMPERATURA ADECUADO, TALES MATERIALES SON TAMBIEN REQUERIDOS PARA SATISFACER TODOS LOS REQUERIMIENTOS BAJO TENSION DE CORRIENTE DE CORTOCIRCUITO. ESTO SE CONSIGUE MEDIANTE LA INVENCION, DE TAL MODO QUE SE AÑADEN DE FORMA SEPARADA OTROS OXIDOS METALICOS AL OXIDO DE ESTAÑO Y/O DE HIERRO, CONTENIENDO AL MENOS UN ELEMENTO DEL SEXTO SUBGRUPO DEL SISTEMA PERIODICO. EL OTRO OXIDO METALICO DEL MATERIAL COMPUESTO SINTERIZADO DE LA INVENCION ES EN PARTICULAR WOLFRAMATO FERRICO (FEWO4). CON PREFERENCIA SE DISPONE DE SNO2 MEZCLADO DE FORMA SEPARADA EN COMBINACION CON FEWO4. PARA PRODUCIR TALES MATERIALES COMPUESTOS SINTERIZADOS, SE OBTIENE UN POLVO DE ALEACION OXIDADO INTERNAMENTE A PARTIR DE UNA ALEACION AGSNBICU Y SE MEZCLA CON EL POLVO DE OTRO OXIDO METALICO U OXIDOS Y LA MEZCLA DE POLVO ES SINTERIZADA EN MOLDES CON UNA POROSIDAD MENOR DEL 1,5 %.
