On the existence of cerium monocarbide: cerium nitride carbides

Journal of Inorganic and Nuclear Chemistry, 1969
Abstract Re-examination of the binary system Ce-C gave no evidence for the existence of any phase structurally based on monatomic (methanide) anions, but the C22− anions of Ce2C3 appear to undergo reversible dissociation to methanide anions at high temperatures (1800–2000°C). The ternary system Ce-C-N is complex. Both tetragonal CeC2 and b.c.c. Ce2C3

The Phase Diagram of the Cerium-Cerium Trichloride System

The Journal of Physical Chemistry, 1959
The solubility of cerium in cerium trichloride is 9.3 mole% with a temperature coefficient of nearly zero between 777 and 950 deg C. The solubility of CeCl/sub 3/ in ceis not greater than 0.2 mole % at 950 EC. Above 777 deg C and 9.3 mole% added cerium the system consists of two immiscible liquids in equilibrium and has a consolute temperature that is ...

The electronic state of cerium in thorium-cerium alloys

Journal of the Less Common Metals, 1962
Abstract In spite of the fact that the atomic diameter of normal γ-cerium exceeds that of thorium, the lattice spacing/composition curve for the thorium-cerium system contains a minimum at approximately 26 at. % cerium. Possible reasons for this behaviour are discussed, and it is concluded that it is justifiable to regard the contraction of the ...

Near Edge Structure in Cerium and Cerium Compounds

1983
The L absorption spectra of γ- and α-Ce and of some Ce alloys have been measured. The L2 and L3 spectra show white lines. Those systems in which Ce is compressed exhibit an additional peak (α peak) above the white line. We deduce that α-Ce is not valence fluctuating and that the α peak in α-Ce is due to a core hole mediated excitation of the 4f ...

Cerium and cerium intermetallics: 4f-band metals?

Physica B+C, 1985
Abstract The applicability of band theory to the description of the 4f electrons in Ce and its intermetallic compounds is considered. The convincing experimental and theoretical evidence that α-Ce is indeed a 4f-band metal, as first suggested by Gustafson and his collaborators, is reviewed, and the results of recent band calculations of the ground ...

Cerium under the lens

Nature Chemistry, 2013
Eric J. Schelter ponders on cerium's rather puzzling redox reactivity, and the varied practical applications that have emerged from it.
