MASAYASU TOKONAMI1966 Volume 4 Issue 6 Pages 401-423

JOURNAL FREE ACCESSThe structure of the 96R polytype of SiC was investigated with the use, of X-ray diffraction photographs. Taking advantage of the fact that the structure of every polytype of this material consists of identical layers, a direct method was deviced to determine the sequence only from semi-quantitative intensity data. The method was successfully applied, and the structure thus deduced is (3333333434)3 in the Zhdanov symbol.View full abstractDownload PDF (2240K) -
YOSHIO TAKÉUCHI, RYOICHI SADANAGA1966 Volume 4 Issue 6 Pages 424-437

JOURNAL FREE ACCESSThe crystal structure of xanthophyllite was refined by least squares with 384 F0(hkl). The results established the detailed configuration of the (Al3Si)O10 sheet and showed an evidence of ordering of cations in the octahedral positons. The average bond lengths determined are: Al3Si-O, 1.730±0.014Å; Al, Mg-O, 2.016±0.011Å; Mg-O, 2.072±0.014Å; Ca-O, 2.410±0.012Å.View full abstractDownload PDF (558K) -
HIDEO OTSU1966 Volume 4 Issue 6 Pages 438-464
Published: 1966
Released on J-STAGE: March 18, 2008
JOURNAL FREE ACCESSThe integrated intensities of diffraction by oriented powder specimens were studied for the case of X-ray diffractometry, with particular reference to the orientation of single crystals in the specimens. From geometrical considerations, an intensity formula with a term concerning the orientation was deduced, and to confirm the formula, the basal reflections of several flat specimens of muscovite and illite with various modes of orientation were examined.View full abstractDownload PDF (893K)
