The results of the hydrogenation of Shubarkol coal with an applied catalytic additive of iron chloride and a polymer as a solvent and a source of hydrogen are described. The donor properties of the polymer in the process ...

For the first time double ferrites from terbium oxide, iron carbonates, and alkaline earth metals were synthesized using a solid phase procedure. Symmetry and unit cell parameters of the synthesized compounds were determined ...

Double ferrites were synthesized by solid-phase annealing from thulium and iron oxides and alkaline-earth carbonates for the first time. Their symmetry systems and unit cell parameters were determined by X-ray diffraction ...

The Tm2M 3 I Fe5O12 (MI = Li, Na, K) compounds have been prepared for the first time by solid-state reactions between thulium(III) oxide, iron(III) oxide, and alkali metal carbonates, and their symmetry class and unit-cell ...
