Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA SEPARACION DE CALCIO Y NITROGENO DEL LITIO. ESTE PROCEDIMIENTO SE CARACTERIZA PORQUE SE AÑADE ALUMINIO AL LITIO FUNDIDO PARA FORMAR NITRURO DE ALUMINIO Y OXIDO DE CALCIO INSOLUBLES Y SE SEPARAN EN CALIENTE DICHOS INSOLUBLES PARA RECUPERAR EL LITIO PURIFICADO. ENCUENTRA APLICACION EN LA OBTENCION DE LITIO DE CALIDAD ESPECIALMENTE APTA PARA LA FABRICACION DE ALEACIONES DE ALUMINIO-LITIO Y DE ELECTRODOS DE BATERIAS ELECTRICAS.
