Low Temperature Anharmonicity in the Superconducting Spinels [PDF]
Strong comparisons between the properties of the high transition temperature superconductors in the β- tungsten and NbN groups and the superconducting spinels are described within the framework of present theories of high Tc superconductivity.

Thermal expansion behaviour of some oxide spinels [PDF]
Compounds which crystallize with the cubic spinel structure are believed to be unusually anharmonic. This work is concerned with investigating the anharmonicity in MgA 204 and ZnFe204 spinels.

Ferric iron in chrome-bearing spinels: implications for microprobe correction procedures
We investigated the compositions of a suite of 361 chrome-bearing spinels from spinel peridotites, ophiolitic mantle chromitites and from layered igneous intrusions in which the Fe2+/Fe3+ ratio has been determined by Mössbauer spectroscopy.

Probing magnetic order in EELS of chromite spinels using both multiple scattering (FEFF8.2) and DFT (WIEN2k) [PDF]
The electron energy loss near edge structure on the O K-edge from chromite spinels contains fine structure from the hybridisation of the O p-orbitals and the Cr d-orbitals.

Cr-spinels from ultramafic rocks from Lokris (Megaplatanos and Tragana), and Beotia (Ypato and Alyki) ophiolitic occurrences were studied. These rocks comprise principally harzburgite with minor dunite. Small amounts of clinopyroxene-rich harzburgite and

The (Cu,Mn,Co)3O4 (CMC) spinel layer is useful in inhibiting Cr vaporization that deteriorates the solid oxide fuel cell performance. The effectiveness of the spinel layer in suppressing volatile Cr species from the metallic interconnects is strongly ...

Use of dilatometer to screen refractory raw materials
Sudden shortage of a particular raw material due to freight disruptions, competitive market, and COVID restrictions have frequently forced the refractory industry to rapidly develop alternative formulations using available low‐cost materials.
