Zirconium selenides

The existence of the zirconium selenides ZrSe(cr), ZrSe 5(cr), ZrSe2(cr), and ZrSc3(cr) have been reported. No experimental thermodynamic data are available except for ZrSesCcr) for which the heat capacity has been measured in the temperature range 8 to 200 K [86PRO/AYA]. These temperatures are too low for a derivation of thermodynamic quantities at 298.15 K. Mills [74MIL] has estimated some thermodynamic values by comparison with the corresponding sulphides and tellurides.

The main problem in developing fibers for IR transmission is that silica glass is not transparent in that area of the spectrum. Suitable materials include the selenides and other chalcogenide glasses (particularly for the CO2 laser light source) and the fluorohafnate glasses. In addition, materials, such as zirconium fluo-...

Similarly, irradiation of the complexes ZrCp2(EPh)(CH3) (E = S or Se) in the presence of added selenoether resulted in the substitution of the methyl ligand by selenide [Eq. (36)] (40c). The authors suggested that this reaction proceeded via zirconium-methyl bond homolysis. 

In addition to the above, preparation in w/o microemulsions of nanoparticles of various other types of compounds, viz. silica-coated iron oxide, Fe203-Ag nanocomposite, oxides of ytrium, erbium, neodymium, vanadium and cobalt, titanates of barium and lead, ferrites of barium, strontium, manganese, cobalt and zinc, oxide superconductors, aluminates, zirconium silicate, barium tungstate, phosphates of calcium, aluminium and zinc, carbonates of calcium and barium, sulphides of molybdenum and sodium, selenides of cadmium and silver etc. have been reported. Preparative sources and related elaboration can be found in [24].
