Abstract

"PROCESSO PARA PRODUZIR UM POLIFOSFATO DE METAL ALCALINO". Um processo para produzir um polifosfato de metal alcalino, compreendendo aquecer uma solução constituída de um solvente, íons de metal alcalino, íons de fosfato, e 3 a 50% em peso de matéria orgânica, em que a solução contém, no total, de 5 a 65% em peso dos íons de metal alcalino e dos íons de fosfato, e a relação M/P é de 1,0 a 3,0, em que M é o número de moles de íons de metal alcalino na solução, e P é o número de moles de íons de ortofosfato na solução, em uma temperatura de 800 a 1200‹C, na presença de excesso de ar, opcionalmente depois a solução é pelo menos parcialmente secada a sólido, para produzir o polifosfato de metal alcalino.
