The effects of forming pressure and sintering temperature on shrinkuge, density, and phase composition of α- and β-SiC were determined. Alpha SiC developed the 4H phase at the expense of the 6H phase at >2150°C. The beta form converted to the 6H p

X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) have been used to follow the effect of calcination temperature on CeO2 particle size, relative CeO2 concentration, and cerium oxidation state for CeO2 supported on γ-Al2O3. When the

The objective of this study is to investigate the structure of the Pd-La/α-Al2O3 catalyst. X-ray diffraction (XRD) and temperature-programmed reduction (TPRd) were used as characterization techniques. Contrary to the assertions in the literature, XR

The La2O3/Al2O3 composite oxides were characterized in terms of their point of zero charge (pzc) and surface area. A model, describing lanthana dispersed as hemispherical clusters, was used to analyze the results. The model parameters calculated from

The addition of ceria, CeO{sub 2}, to automotive exhaust-gas catalysts has been linked to greater thermal stability of the alumina support, higher precious-metal dispersion, and wider range of parameters for three-way operation. Some, if not all, of
