Effect of iron on the properties of sulfated zirconia
(Elsevier Science, 2008-12)
Sulfated zirconia has found several industrial applications, mainly for catalyzing reactions which require acidic sites. In order to control the properties of this solid, the effect of iron on the sulfated zirconia properties ...
Estudo da zircônia reforçado com alumina
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2008-12-29)
Ceramics materials have good properties including chemical stability, high hardness and wear resistance. Moreover, due to its fragility, can suffer failure under relatively low levels of tension. Actually zirconia is the ...
Avaliação da resistência de união entre infra-estrutura de zircônia e cerâmica de cobertura comparado com um sistema metalo-cerâmico
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2008)
The aim of this in vitro study was to evaluate the bond strength interface between the veneering and core zirconia ceramic of a system metal free compared to metal-ceramic system. For this, 40 blocks were made of zirconia ...
