The structure of BaK0.03Bi0.97O3 by single-crystal X-ray diffraction

Physica C: Superconductivity, 1991
Abstract 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

2016
Single-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.

X‐Ray Diffraction Topography of Zinc Single Crystals

physica status solidi (b), 1969
AbstractCrystal 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

Single-crystal X-ray diffraction study of CaIrO3

American Mineralogist, 2008
Single crystals of CaIrO 3 were prepared via flux growth method. Crystal structure parameters, including the anisotropic displacement parameters, are determined based on a single-crystal X-ray diffraction experiment. The unit-cell dimensions are a = 3.147(2), b = 9.866(6), and c = 7.302(5) A.

Single-Crystal X-Ray Diffraction

1986
Abstract 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.

Single Crystal Goniometer for X-Ray and Neutron Diffraction

Review of Scientific Instruments, 1957
A 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.

X-ray diffraction methods: single crystal

2006
Lattice-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.

Dehydration mechanism in brewsterite: single-crystal X-ray diffraction study

Microporous and Mesoporous Materials, 2000
Abstract The crystal structure of the zeolite brewsterite (space group P2 1 /m, ideal formula (Sr,Ba) 2 Al 4 Si 12 O 32  · 10H 2 O) was studied at different dehydration levels. Six single crystals were kept in evacuated capillaries at different temperatures and for different treatment times, and the X-ray diffraction data were collected at room ...
