Interest in nanocrystaJline ceramic powders is due to their attractive processing and mechanical properties. The disadvantages of conventional ceramics, such as large internal flaws, negligible ductility, hightemperature processing, can possibly be eliminated or minimized by starting with finegrained powders. A previous study on the sinterability of nanocrystalline ceramic powders showed that h...

This paper presents experimental data and its interpretation regarding the forming of YAG spinel green-bodies, intended for transparent parts fabrication, by pressure slip casting (PSC) method. Conditions an optimal operation are established based on modeling filtration kinetics. It emerges that method is able to provide highly sinterable green ensuring cakes porosity exhibits low average size ...

Fine reactive alumina powders have a significant impact on the properties of refractories at high temperatures. Except for hydration cement and in situ reactions, performance castables is also correlated with sintering alumina. The characteristics fine produced by various manufacturers are quite different. This work aims to investigate comprehensive influence powder behaviour powders. Three typ...

The elastic properties of 0, 10, 15, and 20 mol% yttrium-doped barium zirconate (BZY0, BZY10, BZY15, BZY20) at the operating temperatures protonic ceramic fuel cells were evaluated. proposed measurement method for low sinterability materials could accurately determine sonic velocities small-pellet-type samples, determined based on these velocities. Young’s modulus BZY20 was 224, 218, 209 GPa °C...

Ceria (CeO2) is an important rare earth oxide and has been widely investigated in the automotive exhaust puri cation, oxygen storage and release catalysis, and solid oxide fuel cell applications. In recent years, due to the excellent physical and chemical properties of nanosized particles, which are signi cantly different from those of bulk particles, there is considerable interest in enhancing...
