Abstract
"DISPERSãO COLOIDAL AQUOSA, PROCESSO DE PREPARAçãO DE UMA DISPERSãO, E, UTILIZAçãO DE UMA DISPERSãO" A invenção refere-se a uma dispersão coloidal aquosa à base de pelo menos um composto de um lantanídeo e de um complexante apresentando um pK (co-logaritmo da constante de dissociação do complexo formado pelo complexante e o cátion lantanídeo) superior a 2,5. Esta dispersão pode compreender, adicionalmente, um composto de pelo menos um elemento selecionado dentre os grupos IVa, Va, VIa, VIIa, VIII, Ib e IIb da classificação periódica. O processo de preparação da dispersão parte de uma mistura aquosa compreendendo pelo menos um sal de lantanídeo, um sal de um elemento previamente indicado conforme o caso, e o complexante; em seguida adiciona-se uma base à mistura assim formada e aquece-se a mistura, com o que se obtém a dispersão. A dispersão pode ser utilizada sobre um substrato como agente anticorrosão, em uma composição cosmética, na catálise, na preparação de películas de polímeros, em lubrificação ou nas cerâmicas.
