Used in the preparation of Si3N4 components, rare-earth elements promote the growth of needlelike grains essential to elevated toughness; evidently, La is significantly more effective than Lu. To explore this difference, we determine the three-dimens

The viscosity behavior of extrusion pastes comprised of a PVB melt and varying amounts of nano-zirconia powder have been explored with special emphasis on the impact of a dispersant to reduce the viscosity. In contrast to suspensions with nanopowders

The silicon oxynitride glasses take advantage of nitrogen-bonding to attain high elastic modulus, increased softening temperatures and viscosities, greater slow crack growth resistance and modest gains in fracture resistance. Of the oxynitride glasse

The mechanical behavior of four rare earth (RE)-Mg-doped Si 3 N 4 ceramics (RE = La, Lu, Y, Yb) with varying grain-boundary adhesion has been examined with emphasis on materials containing La and Lu (which represent the extremes of RE ionic radius).

Two series of oxynitride glasses, RE–Si–Mg–O–N ( M = Mg , Al ; RE = La , Lu), have been studied by X-Ray photoelectron spectroscopy (XPS). The oxygen 1s photoelectron lineshape reveals a striking difference depending on the rare earth, both i
