This paper deals with numerical simulations of some capillary-driven flows. The focus is on
the wetting phenomenon in sintering-like flows and in the imbibition of liquids into a porous …

The combination of Al 2 O 3 and CeO 2 was testified as suitable sintering additive for liquid
phase sintering of SiC ceramics, which has lower sintering temperature than that sintered …

Silicon carbide (SiC) ceramics have been fabricated by pressureless liquid phase sintering
with Al 2 O 3 and rare-earth oxides (Lu 2 O 3, Er 2 O 3 and CeO 2) as sintering additives …

The effectiveness of sintering additives for β-SiC was examined based on thermodynamic
calculations and experimental observations under hot pressing conditions of 1700–1800° C …

Em função da corrosão acentuada apresentada pelos refratários utilizados nos processos
siderúrgicos e diante da necessidade de se tentar minimizar e entender as interações entre …

Wettability is the most significant phenomenon in SiC liquid phase sintering. The wetting of
Y2O3/Al2O3 and Sm2O3/Al2O3 on SiC was analysed by the “Sessil drop” method. The …

This paper examines a range of metal oxides, including those containing relatively safe
elements under neutron irradiation, such as Cr, Fe, Ta, Ti, V and W, as well as widely used …

β-SiC ceramics were prepared by spark plasma sintering at 2200° C with Y 2 O 3, MgO, and
CeO 2 as sintering additives. Al 2 O 3 was doped based on the above oxides to form a two …

Silicon carbide is recommended for applications in energy technology due to its good high-
temperature corrosion resistance, mechanical durability, and abrasion resistance. The …

Some materials-related microstructural problems calculated using the phase-field method
are presented. It is well known that the phase field method requires mesh resolution of a …
