There was a wide distribution in size and compositions of individual phases in the block, depending on the cooling history in the different parts of the block.

It is a ferroelectric ceramic material that exhibits the. domain is removed, thereby forming periodically inverted 180 deg. Barium titanate appears white as a powder and is transparent when prepared as large crystals. The phase compositions were evaluated in detail by SEM and EPMA, and the partitioning of key fission product elements in the different phases was evaluated and compared with those in ceramic route Synroc. PURPOSE:To increase the length of the waveguides for coupling without attenuating light and to eliminate distortions and noises so as to improve an amplification rate by impressing prescribed electric fields to the BaTiO3 single crystal from which 90 deg. OM and SEM investigations showed the presence of some additional phases, such as alkali and alkaline-earth molybdates, Ca-Al-Ti oxide phase and hibonite. Lastly, this trend is consistent with the phase assemblage observed in Synroc, where Cs +, Rb + and Ba 2+ enter into hollandite, whereas Sr 2+ occurs in = ) were observed in both the quenched and slowly-cooled samples. Electronic Structure of Sr-Doped LaScO3 Single Crystal Annealed under. In order to estimate second-order nonlinear optical coefficient d (2), Maker fringe patterns of the BaTiO 3-containing glass-ceramics were analyzed. Further energetic analysis with respect to BaTiO 3 and SrTiO 3 perovskites and other oxides reveals decreased thermodynamic stability from Cs- to Rb- to Sr-hollandite. Surface ElectronIon Mixed Conduction of BaTiO3-d Thin Film with Oxygen Vacancies. These facts suggest that BaTiO 3 crystal is responsible for the second-order nonlinear phenomenon, although its structure is closer to cubic than tetragonal according to x-ray diffraction measurements. Their formation enthalpies are similar, consistent with the occurrence of extensive cation substitutions in hollandites. Standard enthalpies of formation of these hollandites were determined from drop solution calorimetric measurements with lead borate as the solvent at 973 K.

Rietveld analysis of synchrotron XRD data shows that they adopt the tetragonal structure (space group I4/m), and their cell parameters increase with increasing cation size (Sr 2+ → Rb + → Cs +). Titanate hollandites are of considerable interest for immobilization of radioactive Cs, its daughter product Ba and related radionuclides Rb and Sr.
