Abstract

"ESCóRIA à BASE DE SILICATO DE CáLCIO, MéTODO PARA PRODUZIR A MESMA E USO DA MESMA". A presente invenção refere-se a uma escória à base de silicato de cálcio tendo um teor de fósforo menor do que 3 ppm/peso. A invenção ainda refere-se a um método para produzir uma escória à base de silicato de cálcio de baixo teor de fósforo, onde escória à base de silicato de cálcio em fusão é tratada com uma liga de ferro-silício em fusão em um vaso, assim fósforo na escória à base de silicato de cálcio é transferido para a liga de ferro-silício, e uma escória à base de silicato de cálcio de baixo teor de fósforo é removida do vaso.
