Abstract

"MAGADIITA E OCTOSSILICATO SINTéTICOS EM ESCAMAS". Método para produzir magadiita sintética, incluindo a etapa de: aquecer uma suspensão de sílica coloidal aquosa líquida, a suspensão de sílica coloidal aquosa líquida tendo uma razão molar de hidróxido de sódio para sílica e uma razão molar de água para sílica eficazes para produzir uma magadiita sintética sendo que mais que cinq³enta por cento em peso da magadiita sintética é magadiita sintética em escamas. A magadiita sintética em escamas pode ser convertida para a forma ácida e: (a) aquecida para produzir placas como quartzo, ou (b) alquilada para produzir um material organofílico. Em outro aspecto, a invenção presente é um método para a produção de octossilicato de sódio em escamas que inclui a etapa de: aquecer uma dispersão de sílica coloidal aquosa líquida contendo sílica, óxido de sódio, e água, a razão molar da sílica para o óxido de sódio estando na faixa de cerca de 3,5 até 10. Em outro aspecto, a invenção presente é um método para preparar uma dispersão de sílica coloidal aquosa líquida, a dispersão tendo uma razão molar de sílica para óxido de sódio de 3,5 até 10, que inclui a etapa de: misturar uma quantidade suficiente de suspensão de sílica coloidal aquosa líquida com uma suspensão de silicato de sódio aquosa líquida para produzir a dispersão de sílica coloidal aquosa líquida, a suspensão de sílica coloidal aquosa líquida tendo uma razão molar de sílica para óxido de sódio de mais que 20, a suspensão de silicato de sódio aquosa líquida tendo uma razão molar de sílica para óxido de sódio de menos que 3,5, a taxa de misturação sendo eficaz para impedir a gelificação ou solidificação da dispersão de sílica coloidal aquosa líquida.
