The subsolidus phase diagram CaO–Al 2 O 3 –Ta 2 O 5 has been determined at 1300–1350°C. Two ternary phases are present, Ca 2 AlTaO 6 and the new phase, CaAlTaO 5 . From Rietveld refinement of powder X-ray diffraction data, CaAlTaO 5 has the sphene structure, monoclinic 6.676...
The crystal structure and defects in a commercial TWS-100 β-SiC whisker were observed and analyzed by means of high-resolution transmission electron microscopy. It was found that the SiC whiskers with triangular or hexagonal cross-sections both have a face-centered cubic structure, while their cry...
The crystal structure of AFm phases is composed of positively charged main layers [Ca2Al(OH)6]+ and negatively charged interlayers [X·nH2O]− where X is one monovalent anion or half a divalent anion. The following general formulae 3CaO∙Al2O3∙ CaX2∙ nH2O for a monovalent anion...
In this letter, we report the crystal structure manipulation of the exchange bias in epitaxial hcp Cr2O3 films. By epitaxially growing twined (1010) oriented Cr2O3 thin films, of which the c axis and spins of the Cr atoms lie in the film plane, we demonstrate that the exchange bias ...
