γ-Alumina: a single-crystal X-ray diffraction study
Acta Crystallographica Section C Crystal Structure Communications, 2006The structure of gamma-alumina (Al21+1/3square2+2/3O32) crystals obtained as a product of a corrosion reaction between beta-sialon and steel was refined in the space group Fd3m. The oxygen sublattice is fully occupied. The refined occupancy parameters are 0.83 (3), 0.818 (13), 0.066 (14) and 0.044 (18) for Al ions in 8a, 16d, 16c and 48f positions ...

Single crystal X-ray diffraction of the quasi crystal Al6CuLi3
Solid State Communications, 1987Results of a single crystal X-ray diffraction study of the quasi crystal Al6CuLi3 are presented. The positions of the reflections are accurately determined, and found to be in accordance with the icosahedral point group symmetry in very good approximation. The six reciprocal axes could uniquely be assigned, and a length of 0.4203 Å-1 is determined. The

A furnace for X-ray diffraction studies of single crystals
Journal of Physics E: Scientific Instruments, 1973A miniature furnace suitable for the collection of single crystal x-ray diffraction data at temperatures between room temperature and about 200°C is described. The device was primarily designed for solid-state phase transformation investigations, but may be used for general diffraction studies. Commercially available goniometer heads require only minor

The structure of BaK0.03Bi0.97O3 by single-crystal X-ray diffraction
Physica C: Superconductivity, 1991Abstract We determined by x-ray diffraction the structure of a slightly K-doped BaBiO 3 single-crystal. The best refinements were obtained by describing the structure in the monoclinic 12/m space group similarly to the structure of the undoped compound.

Single-Crystal X-ray Diffraction
2016Single-crystal X-ray diffraction is an extremely powerful technique to characterize small drug molecules in solid form. It is a mature technique that is becoming ever more automated, and it is increasingly viewed as “routine” in both industry and academia.

Single-Crystal X-Ray Diffraction
1986Abstract The primary goal of single-crystal x-ray diffraction is to determine crystal structure and the arrangement of atoms in a unit cell. This article discusses the diffraction of light through line gratings and explains the significance of crystal symmetry, space groups, and diffraction intensities.

X‐Ray Diffraction Topography of Zinc Single Crystals
physica status solidi (b), 1969AbstractCrystal imperfections in zinc single crystals were studied by X‐ray topography. The zinc single crystals were obtained in a glass ampule from a molten droplet which, after solidification, acted as a nucleus for further growth from the vapour phase. The crystals adhered strongly to the glass support. The X‐ray topographs give informations on the

X-ray diffraction methods: single crystal
2006Lattice-parameter determination using X-ray diffraction methods on single crystals is reviewed. All the methods are classified with respect to the measurement technique, in particular into photographic and counter-diffractometer techniques. The methods are described in approximately chronological sequence, i.e.

Single Crystal Goniometer for X-Ray and Neutron Diffraction
Review of Scientific Instruments, 1957A single crystal goniometer intended both for x-ray and neutron diffraction analysis has been used in neutron diffraction work at the Kjeller reactor. The unique feature of this goniometer is a macromodel of the unit cell designed for easy orienting of the crystal.
