Abstract

PROCESSO PARA A MANUFATURA DE UM PRODUTO MESOPOROSO, PRODUTO DE CERÂMICA E DISPOSITIVO. Processo para a manufatura de um produto mesoporoso compreendendo as seguintes etapas sucessivas: a) preparação de uma argila líquida compreendendo: um solvente, um aditivo, mais que 4%, como percentagem em volume baseado na argila líquida, de uma poeira formada de partículas de cerâmica, b) congelamento orientado da argila líquida, de modo a formar um bloco compreendendo cristais de gelo separados por paredes, c) remoção dos cristais de gelo de dito bloco de argila líquida congelada, opcionalmente removido do molde, de modo a obter uma pré forma porosa, d) remoção do aditivo, de modo a obter um produto mesoporoso pré-formado, o aditivo e a quantia de aditivo sendo escolhidos de modo que o aditivo esteja presente em uma fase micelar formadora e mesoporos em ditas paredes, mais que 25% em volume de ditas partículas de cerâmica exibindo um tamanho menor que duas vezes o tamanho das micelas de dita fase micelar formadora de mesoporos.
