Abstract

LA INVENCION SE REFIERE A UN SILICIO O FERROSILICIO METALURGICO EN FORMA DE GRANULADOS DE DIMENSION MEDIA INFERIOR A 10 MM, CUYO CONTENIDO TOTAL EN OXIGENO ES INFERIOR A 0,05% EN PESO. SE REFIERE TAMBIEN A UN PROCESO DE FABRICACION DE ESTE SILICIO O FERROSILICIO QUE COMPRENDE: - UNA REDUCCION CARBOTERMICA DE SILICE EN EL HORNO ELECTRICO, - UN AFINADO CON CLORO DEL METAL LIQUIDO OBTENIDO, - UNA GRANULACION CON AGUA BAJO ATMOSFERA INERTE DEL METAL LIQUIDO AFINADO. EL SILICIO SEGUN LA INVENCION PUEDE UTILIZARSE PARA LA FABRICACION DE SILICONAS O COMO ELEMENTO DE ALEACIONES DE ALUMINIO, Y EL FERROSILICIO COMO ADITIVO AL ACERO PARA OBTENER CHAPAS MAGNETICAS PARA LA CONSTRUCCION ELECTRICA.
