2021年5月15日 Barium hollandites may exhibit long-range ordering of barium cations and vacancies in the tunnels and have the possibility to be commensurate . In addition, the diffraction peaks with remarkable broadening revealed the crystallinity in the nanoscale regime of the sample of BT1-900 particles. Therefore, the crystalline size was calculated 2006年3月15日 The U.S. Department of Energy's Office of Scientific and Technical InformationSynthesis and characterization of the pseudo-hexagonal These hollandites display commensurate and incommensurate superlattices owing to the ordered insertion of large cations (Ba 2+, Cs +) into the (2, 2) tunnel interstices of the octahedral (Al, Ti) O 6 framework. Multiplicity (m) of a supercell is defined as d supercell divided by d 002 for the subcell. Ordering may be one-dimensional, in which[BaxCsy [(Ti, Al)3+2x+y Ti4+8-2x-y] O16 Synroc-type
