Abstract

UN PROCESO PARA DETERMINAR EL CONTENIDO DE CIRCONIO DISUELTO EN UN BAÑO (7) PARA GRABAR EL AGUA FUERTE DE ACIDO NITRICO - ACIDO FLUORIZADO PARA ARTICULOS DE CIRCONIO DETERMINANDO EL AUMENTO DE TEMPERATURA DE UN VOLUMEN DEL BAÑO (7) POR INMERSION DENTRO DEL DE UNA CANTIDAD CONOCIDA DE METAL DE CIRCONIO (15) SUMERGIENDO UNA CANTIDAD CONOCIDA DE METAL DE CIRCONIO (15) EN UNA PORCION DEL BAÑO (7), MIDIENDO EL AUMENTO DE TEMPERATURA EN UN PERIODO PREDETERMINADO DE TIEMPO DE DICHA PORCION (7), DETERMINANDO EL CONTENIDO DE CIRCONIO DISUELTO DEL BAÑO (7) COMO UNA FUNCION DEL AUMENTO DE TEMPERATURA Y TRATANDO EL BAÑO (7) DEPENDIENDO DEL CONTENIDO DE CIRCONIO DISUELTO QUE SERA DETERMINADO EN EL BAÑO (7).
