  • Synthesis of hexacelsian Barium aluminosilicate by film boiling chemical vapour process
    Journal of the European Ceramic Society, 2020
    Co-Authors: C. Besnard, A. Allemand, P. David, Laurence Maillé
    Abstract:

    An original oxide/oxide ceramic-matrix composite containing mullite-based fibers and a Barium aluminosilicate matrix has been synthesized by the film boiling chemical vapour infiltration process. AlkOxides were used as liquid precursors for aluminum, silicon and Barium Oxides. The structure and microstructure of the oxide matrix were characterized by Scanning Electron Microscopy, Energy Dispersive Spectroscopy and X-ray diffraction. Apart from small residual mullite and amorphous phase amounts, the oxide matrix is composed of the hexacelsian phase, conferring to the material interesting perspectives for high-temperature electromagnetic and structural applications.

  • Thermodynamic properties of ternary Barium Oxides
    Thermochimica Acta, 1995
    Co-Authors: Tsuneo Matsui
    Abstract:

    Abstract The vapor pressure over the two-phase mixture of CeO 2 + BaCeO 3 has been measured by mass spectrometry in the temperature range 1774–1947 K. BaO(g) only was identified as being the main gas species. From the vapor pressure of BaO(g) over CeO 2 + BaCeO 3 , the standard molar enthalpy of formation of BaCeO 3 has been determined by second and third law treatments and is compared with those values calculated by the use of Aronson's semiempirical equation in this study and obtained previously by solution calorimetry. The standard molar Gibbs energies of formation of BaCeO 3 , BaZrO 3 and Ba 2 ZrO 4 have also been determined as a function of temperature from the respective vapor pressures of BaO(g) over CeO 2 + BaCeO 3 in this study and those over ZrO 2 + BaZrO 3 and BaZrO 3 + Ba 2 ZrO 4 previously determined by the present author and co-workers. The experimental values of the standard molar Gibbs energy of formation and the standard molar enthalpy of formation of other ternary Barium Oxides such as BaMoO 3 , BaMoO 4 , BaUO 3 , BaUO 4 , BaTiO 3 , Ba 2 TiO 4 , BaThO 3 and BaPuO 3 are summarized and the latter is compared with calculated values from Aronson's equation. The relative stability of Barium perovskite Oxides is briefly discussed from the Goldschmidt tolerance factors and the molar enthalpies of formation of the perovskite Oxides from the constituent binary Oxides.
