Abstract

LA HEXAFLUOROFOSFATO SE PUEDEN UTILIZAR COMO ESTRUCTURAS QUE AFINAN EL GRANO DURANTE LA SOLIDIFICACION DE ALEACIONES DE AL SI FUNDIDAS. SU EFECTO SE OBTIENE CASI INMEDIATAMENTE DESPUES DE LA ADICION DEL HEXAFLUOROFOSFATO A LA ALEACION FUNDIDA. EL FLUOROFOSFATO SE UTILIZA PREFERIBLEMENTE EN FORMA DE UNA COMPOSICION PATRON EN DONDE SE USAN METALES DILUENTES, SOBRE TODO COBRE.
