Abstract

ARTIGO CERÂMICO E PROCESSO DE PRODUÇÃO DO MESMO. É revelado um processo para a produção de partículas cerâmicas, tais como escoramentos que tenham pelo menos 10 porcento de porosidade total. O processo inclui a formação de um precursor de partícula que inclui 5 porcento a 30 porcento de um primeiro material cerâmico e pelo menos 40 porcento de um segundo material cerâmico. A temperatura de sinterização do primeiro material cerâmico pode ser inferior à temperatura de sinterização de um segundo material cerâmico. O aquecimento do precursor para uma temperatura máxima acima da temperatura de sinterização do primeiro material e abaixo da temperatura de sinterização do segundo material. Também é revelado um artigo cerâmico que tem uma combinação particular de química e de fase cristalina de alumina.
