Cerâmicas porosas autoligadas de alumina-mulita obtidas a partir de suspensões de aluminas de transição e sílica coloidal

Abstract: Agradeço meu orientador, Prof. Dr. Rafael Salomão pelo acolhimento, paciência e confiança não somente durante o período que pudemos trabalhar juntos, mas também por viabilizar a finalização do meu mestrado. Sou grata pela inspiração e exemplo de um ótimo professor, com dedicação ao ensino e à pesquisa, sempre com atitudes corretas e justas as quais levarei para toda a minha carreira. Às agências de fomento pelo financiamento da pesquisa. O presente trabalho foi realizado com apoio da Coordenação de Aperfeiçoam… Show more

“…Therefore, based on these considerations, the present work aimed to obtain porous ceramics structures of high densification resistance for application as thermal insulators that show total porosity levels above 50 % [7], average pore size ranging between 0,5-5 μm [23], flexural elastic modulus above 2GPa [24], flexural strength above 0.5 -1 MPa [24], linear shrinkage lower than 15% after sintering at 1500°C and thermal conductivity below 2 W(m•K) -produce such structures using previously sintered Al(OH)3 as raw-material.…”
