Abstract

COMPOSIÇÕES CONTENDO ZIRCÔNIO E CÉRIO E MÉTODOS PARA PREPARAR AS MESMAS USANDO ÁCIDO OXÁLICO E SECAGEM SUPERCRÍTICA. São divulgadas aqui composições contendo zircônio e cério com um tamanho de partícula surpreendentemente pequeno. As composições divulgadas aqui contêm zircônio, cério, opcionalmente ítrio e opcionalmente um ou mais outros óxidos de terras raras diferentes de cério e ítrio. As composições exibem um tamanho de partícula tendo como característica um valor de D90 de cerca de 5 µm a cerca de 25 µm e um valor de D99 de cerca de 5 µm a cerca de 50 µm. São ainda divulgados processos de produção destas composições usando ácido oxálico e secagem supercrítica no processo. As composições podem ser usadas como catalisador e/ou parte de um sistema catalítico.
