Durability of feldspathic veneering ceramic on glass-infiltrated alumina ceramics after long-term thermocycling.
(2010-07-01)
This study compared the bond strength durability of a feldspathic veneering ceramic to glass-infiltrated reinforced ceramics in dry and aged conditions. Disc shaped (thickness: 4 mm, diameter: 4 mm) of glass-infiltrated ...
Palladium-supported catalysts in methane combustion. Comparison of alumina and zirconia supports
(Brasil, 2012)
Palladium catalysts supported on alumina and zirconia were prepared by the impregnation method and calcined at 600 and 1000 ºC. Catalysts were characterized by BET measurements, XRD, XPS, O2-TPD and tested in methane ...

Effect of mechanical cycling on the flexural strength of densely sintered ceramics
(Elsevier B.V., 2014)
Dense mullite zirconia composites obtained from the reaction sintering of milled stoichiometric alumina zircon mixtures by SPS
(Elsevier, 2014-01)
The main objective of this article is to obtain dense (porosity under 0.5%) polyphasic ceramics belonging to the Al2O3–SiO2–ZrO2 system by SPS sintering of high energy powders milled drily; the stoichiometric (54.45:45.54 ...
