Title: Crystal Structure and Phase Transitions of Sr2CdWO6

Abstract

The crystal structure of Sr2CdWO6, prepared by solid state reaction, was determined by high-resolution X-ray diffraction at different temperatures. At room temperature, this compound has a monoclinic structure (space group P21/n) with a=5.7463(1), b=5.8189(1), c=8.1465(1), {beta}=90.071(1). At 1105 K the structure is converted to tetragonal (space group I4/m). Diffraction data also suggest that a cubic phase exists above 1220 K. Comparing the phase transition temperatures of Sr2CdWO6 with those of other compounds of the Sr2MWO6 family reported previously, it was observed that the transition temperatures are higher in compounds with low-tolerance factors. At the same time, the temperature range in which the intermediate tetragonal phase exists is reduced.

  • The structural behavior of a cancrinite, Na{sub 5.96}Ca{sub 1.52}[Al{sub 6}Si{sub 6}O{sub 24}](CO{sub 3}){sub 1.57}{center_dot}1.75H{sub 2}O, was determined by using in situ synchrotron X-ray powder diffraction data [{lambda} = 0.91806(5) {angstrom}] at room pressure and from 25 to 982 {sup o}C. The sample was heated at a rate of about 9.5 {sup o}C/min, and X-ray traces were collected at about 15 {sup o}C intervals. The satellite reflections in cancrinite were lost at about 504 {sup o}C, where a phase transition occurs. All the unit-cell parameters for cancrinite also show a discontinuity at 504 {sup o}C. Initially, the [Ca{center_dot}CO{sub 3}] clusters andmore » their vacancies are ordered in the channels, and this ordering is destroyed on heating to give rise to the phase transition. Cancrinite loses water continuously until about 625 {sup o}C; thereafter an anhydrous cancrinite phase exists. From 25 to 952 {sup o}C, a minimal amount of CO{sub 2} is lost from the structure. Over this temperature range, the average <Al-O-Si> bridging angle, which is an indication of the degree of rotation of the tetrahedra, increases from 143.7(4) to 147.7(5){sup o}. Rotations of the tetrahedra are caused by expansion of the Na1-O2 bond lengths.« less
  • Three linear polyethylenes with branches at every 21st backbone atom have been analyzed by differential scanning calorimetry (DSC) and quasi-isothermal, temperature-modulated DSC. The branches were methyl (PE1M), dimethyl (PE2M), and ethyl groups (PE1E). Linear polyethylene (HDPE) and atactic poly(octadecyl acrylate) (PODA) were also analyzed. All were compared to a random poly(ethylene-co-octene-1) of similar branch concentration (LLDPE) and poly(4,4'-phthaloimidobenzoyldoeicosyleneoxycarbonyl) (PEIM-22). The HDPE has the highest melting temperature and crystallinity with relatively large contributions of reversing melting when grown as folded-chain crystals. The precisely branched polyethylenes and copolymers have lower melting temperatures and heats of fusion. Of the branched samples, PE1M crystallizesmore » more readily, followed by PE1E and PE2M, with PE2M showing cold crystallization. In contrast to paraffins of equal length which melt fully reversibly, the precisely designed, branched polymers melt largely irreversibly with small amounts of reversing melting, which is least for the best-grown crystals. The PE1M forms monoclinic, PE1E, pseudohexagonal, or triclinic crystals, and PE2M has a multitude of crystal structures.« less
  • The response of the mesolite crystal structure (Na{sub 16}Ca{sub 16}Al{sub 48}Si{sub 72}O{sub 240}{center_dot}64H{sub 2}O) to dehydration was evaluated as a function of temperature and partial pressure of water (i.e., P{sub H{sub 2}O} or relative humidity, RH) using laboratory X-ray powder diffraction (XRD; CuK{sub {alpha}} radiation) and synchrotron X-ray pair distribution function (PDF) methods. At 425 C under low-P{sub H{sub 2}O} conditions (P{sub H{sub 2}O} {le} {approx}1.3 mbar), dehydrated mesolite preserved the long-range ordered aluminosilicate framework structure, which has not been previously observed. This new dehydrated phase, x-metamesolite, has unit-cell parameters [a = 16.731(3) {angstrom}, b = 17.822(2) {angstrom}, c =more » 6.312(1) {angstrom}, V = 1882.5(5) {angstrom}{sup 3}, and possible space group Fdd2] similar to those of other dehydrated natrolite phases (either 1- or 2-metanatrolite). Conversely, under high-P{sub H{sub 2}O} conditions (P{sub H{sub 2}O} > {approx}1.3 mbar), dehydrated mesolite became amorphous (amorphous T{sub 5}O{sub 10}) at 425 C. The local structure of amorphous T{sub 5}O{sub 10} was characterized by PDF analyses, which showed the formation of twisted T{sub 5}O{sub 10} nano-fibers [with dimensions (LWH) of {approx}6.9 x 6.9 x 6.3 {angstrom}] resulting from breakage of the mesolite aluminosilicate framework. The two distinct high-temperature P{sub H{sub 2}O}-dependent phase transition paths illustrate the importance of considering the combined effects of temperature and P{sub H{sub 2}O} in mesolite. In addition, the low-temperature phase transition in mesolite, involving order-disorder of the extraframework cations, also showed a P{sub H{sub 2}O}-dependent transition temperature. Although, there is no path dependence on P{sub H{sub 2}O} for this transition, the local arrangement of Na, Ca, and vacancies in disordered metamesolite (formed through the extraframework cation order-disorder phase transition) likely influences the thermal stability of the aluminosilicate framework during further heating.« less
  • The structure of thin films of poly(di-n-propylsiloxane), PDPS, was studied with a combination of optical and atomic force microscopy, electron diffraction, and grazing incidence X-ray diffraction. Two different morphological features are observed in the mesomorphic films. The lamellar ribbons are composed of the chains oriented parallel to the plane of the substrate in which the reciprocal space 10 vector is vertical. The other feature with a circular symmetry, the cylindrite, contains the chains parallel to the substrate normal. The cylindrites and needles are essentially the same mesomorphic lamellae that develop differently under the conditions of confinement. The crystallization of PDPSmore » films does not change the gross morphological features developed during the mesophase formation and mainly proceeds via epitaxial growth of the {alpha}-crystal on the parent mesophase. Spontaneous alignment of the mesomorphic PDPS films on the PTFE-rubbed substrates allows fabricating highly crystalline inorganic polymer surfaces oriented on the scale of centimeters.« less
