AbstractAbstract
[en] Formation of quaternary oxides CaABB'O7 of the composition at A=Ti, Zr, Hf, Sn, B=Al, Ga, Cr, Fe, In, B'=Sb, Nb, Ta is studied. Crystal zirconolite structure has been found in twelve samples containing gallium, ferrum (3) titanium, zirconium, hafnium, niobium, tantalum and antimony (5). In the cases, when A=Sn, B=Al quaternary oxides of the above composition are not formed. It is shown that zirconolite structure stability depends not only on cation dimensions but also on their electron structure

AbstractAbstract
[en] Formation enthalpies of complex perovskite-like oxides and their hexagonal analogs of the composition: Ba2ReFeO6, Sr2ReFeO6, Sr2ReMnO6, Ca2ReMnO6, Sr2WCrO6, Sr2MoCrO6, Ca2MoCrO6, Ca2WCrO6, Ba3Fe2ReO9, Ba3Cr2ReO9, Ba2RhTaO6 and B2ScIrO6 from simple oxides were calculated by approximate method using enthalpies of the cations coordination change in oxygen medium. The conclusion was made that enthalpy stabilization of the oxide with regard to simple oxides is mainly determined by the change in enthalpies of alkaline earth metal cations

AbstractAbstract
[en] Values for standard enthalpies of formation and dissociation energies for gaseous diatomic monoxides have been selected by critical assessment of experimental data from the literature. Gibbs energy functions, (-(G/sup circle-open//sub T/ -H/sup circle-open/298)/T), and enthalpy functions, (H/sup circle-open//sub T/ -H/sup circle-open/298), have been calculated from literature values for molecular parameters. Computer methods of storage, processing and retrieval are described and the resulting data are given in tables 4 to 11

AbstractAbstract
[en] The enthalpies of formation of metal oxides, calculated per oxygen atom, show a dependence on two terms, the work function and the electron density differences between the metal and the oxygen. For the transition metals the first term dominates since the second one seems negligibly small. For non-transition metals the electron density term seems to affect greatly the corresponding enthalpy of formation. (author)

AbstractAbstract
[en] This patent describes an improved process for preparing a superconducting composition. It has the formula MBa2Ox wherein M is selected from the group consisting of Y, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu; x is from about 6.5 to about 7.0. The composition having a superconducting transition temperature of about 90 K. The process consists essentially of heating a precursor powder in an oxygen-containing atmosphere at a temperature from about 875 degrees C to about 950 degrees C for a time sufficient to form MBa2Cu3Oy, where y is from about 6.0 to about 6.4; and maintaining the MBa2Cu3Oy in an oxygen-containing atmosphere while cooling for a time sufficient to obtain the desired product. The precursor powder is prepared by forming an aqueous solution of M(NO3)3, Ba(NO3)2 and Cu(No3)2 in an atomic ratio of M:Ba:Cu of about 1:2:3, adding the resulting solution to sufficient oxalic acid to precipitate the metals present as salts, and spray drying the resulting slurry to obtain the precursor powder
