Neutron diffraction investigation of the temperature dependence of crystal structure and thermal motions of red HgI2.
The structure of, and anisotropic thermal motions in, the red semiconductor tetrahedral layer structure of HgI(2) have been studied with neutron powder diffraction as a function of temperature from 10 to 293 K. Average thermal displacement parameters U(eq) of the two atoms are comparable in size at 10 K, but U(eq)(Hg) increases considerably faster with temperature than U(eq)(I), the Hg-I bond b...
متن کاملNi2As2O7 pyrochlore nanomaterial: Solid state synthesis, crystal structure determination, crystal phase growth study and physical properties
Nanostructured Ni2As2O7 semiconductor samples were synthesized by a solid state method among As2O3 and Ni(NO3)2.6H2O raw materials at 650 °C (S1) and 750 °C (S2) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and F...

متن کاملCrystal structure of (Li0.5K0.5)2C03 by neutron powder diffraction analysis
The crystal structure of (Li0.5K0.5)2C03 was determined by neutron powder diffraction. A final weighted R-factor of 4.54% was obtained for the refinement of 2373 reflections by the Rietveld method from a sample synthesized using 7Li2CO3 and K2CO3 (99.9% pure). Slight distortion of the CO$units in the monoclinic cell was observed; the O( 1)-C-0(2) angle and CO(3) length are larger than those for...
متن کاملThe crystal structure of phlogopite by neutron diffraction
The positions of all the atoms including hydrogen have been found by a partial threedimensional single-crystal neutron-diffraction study in which about one-third of the reflections in the reciprocal sphere to I'5/~ were measured. The hydroxyl group is perpendicular to the plane of the silicate sheets. The fluorine content of this phlogopite is enough to occupy 25 % of the (OH, F) sites. Site oc...
