Abstract

PROCESO DE REALIZACION DE AL MENOS UNA CONEXION DE BAJA RESISTENCIA ELECTRICA ENTRE UN METAL Y UNA PIEZA DE CERAMICA SUPRACONDUCTORA HTC, SIENDO FABRICADA DICHA PIEZA A PARTIR DE POLVO DE CERAMICA QUE SE INTRODUCE EN UN MOLDE, QUE SE COMPRIME Y QUE SE FRITA, CARACTERIZADO POR EL HECHO DE QUE, EN DICHO MOLDE, SE YUXTAPONEN A DICHO POLVO DE CERAMICA, SIN MEZCLARLO CON EL, AL MENOS UN VOLUMEN DE POLVO DE PLATA O DE ORO QUE CORRESPONDE A LA FORMA DE DICHA CONEXION Y QUE ESTA SITUADO EN EL LUGAR DESEADO, Y PORQUE DESPUES DE LA COMPRESION LA OPERACION DE FRITADO SE EFECTUA BAJO ATMOSFERA QUE CONTIENE OXIGENO A UNA TEMPERATURA INFERIOR A LA TEMPERATURA DE FUSION DE LA PLATA O DEL ORO.
