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.

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

Single-crystal X-ray diffraction study of CaIrO3
American Mineralogist, 2008Single 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
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.

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.

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.

Dehydration mechanism in brewsterite: single-crystal X-ray diffraction study
Microporous and Mesoporous Materials, 2000Abstract 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 ...

CdTe thermal parameters studied by single-crystal x-ray diffraction
Physical Review B, 1987In an earlier paper (Phys. Rev. B 34, 3970 (1986)), the temperature-dependent results of thermal-vibration x-ray studies on a (001)= CdTe crystal have been reported. This note supplements the results mentioned above with additional temperature-dependent data taken on a (111) crystal.
