Abstract

<B>MéTODO PARA EXPANDIR FORMAS LAMELARES DE GRAFITE E PRODUTO RESULTANTE<D> Um método para fabricar grafite expandida a partir de grafite lamelar em flocos compreendendo em primeiro lugar o fornecimento de partículas de grafite lamelar em flocos que têm pelo menos uma pureza mínima, em seguida intercalando as partículas de grafite lamelar em flocos com um composto de intercalação de grafite expansível, seguido pela expansão do composto de intercalação de grafite para esfoliar as partículas de grafite em flocos e finalmente moendo as partículas de grafite esfoliada em flocos para delaminá-las mais adiante.
