Abstract

"DISPERSãO COLOIDAL DE UM COMPOSTO DE CéRIO, PROCESSO DE PREPARAçãO DA MESMA E UTILIZAçãO DA MESMA". A invenção refere-se a uma dispersão coloidal de um composto de cério contendo cério III. Esta dispersão é caracterizada em que ela apresenta uma concentração em óxido de cério de pelo menos 50 g/I, uma taxa de cério III em relação ao cério total de pelo menos 0,5%, uma condutividade de no máximo 5 Ms/cm, um pH compreendido entre 4 e 8 e em que ela é constituída por partículas apresentando um diâmetro médio de, no máximo, 15 nm. Ela é obtida por um processo em que se faz reagir, pelo menos, um sal de cério III com uma base e em presença de um ácido em quantidade tal que a relação H+/Ce seja superior a 1, depois redispersa-se em água o precipitado proveniente da reação precedente. As dispersões deste tipo podem ser utilizadas em catálise, em lubrificação, nas cerâmicas, na fabricação dos compostos luminóforos ou películas de polímeros, na cosmética e como agentes anti-corrosão.
