In: CONGRESO SOCIEDAD ESPANOLA DE CERAMICA Y VITRIO, 50., Octubre 27, 2010, Madrid, Espain. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/18003.http://repositorio.ipen.br/handle/123456789/18003Rare earth porous membranes (RePM) were manufactured by colloidal processing and impregnation method. Ceramic suspensions based on rare earth concentrated (ReC) with 25vol% were prepared. The rheological behavior of ceramic suspensions as function of solid load and binder concentration was evaluated by flow curves with shearing rate interval from 0 to 1000s-1. A nyloncotton netting (NC) was selected as template. Impregnated NC templates were subjected to a careful thermal treatment seeing that burning off the organic template could induce sensible residual stress and disrupting the ceramic structure. Sintering at 1600ºC/15h the morphology of RePMs were like NC templates and presented a good handle strength.openAccessrare earthsrheologysuspensionsimpregnationceramicsporous materialsTexto completo de eventohttps://orcid.org/0000-0002-0155-9100
