Surface superconductivity and structural analysis of YC2 single crystals encapsulated in carbon nanocages. Yosida, Y. (College of Science and Engineering, Department of Environmental Science and Materials Science, Iwaki Meisei University, Iwaki Fukushima 970-8551, Japan).Chemicals with cas numbers 12071-35-1 and 1314-36-9 also play role. Journal of Applied Physics, 92(9), 5494-5497 (English) 2002 American Institute of Physics. CODEN: JAPIAU. ISSN: 0021-8979. DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) Section cross-reference(s): 57, 66, 75 The magnetization measurements at 2-10 K and in the applied fields up to 5 T and x-ray powder diffraction measurement at 293 K for YC2 single crystals encapsulated in C nanocages are reported. The highest crit. field in the magnetization curve near Tc is in excellent agreement with the nucleation field Hc3 for surface supercond. Hc3(2 K), increasing with decreasing mean particle diam., shows an effect of small-particle size of the authors' nanocrystals. No appreciable size dependence of the Ginzburg crit. region is found and suggested to be evidence of the partial suppression of surface supercond. through the contact between YC2 crystals and the innermost nanocages. Structural parameters derived from the Rietveld refinement of the CaC2 model are consistent with those of the bulk YC2. .

DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) A sintering aid chosen from group IIIB or rare earth group element(s) or their hydrides or carbides is used for sintering of a SiC ceramic (contg. 380 mol% SiC) to improved high-temp. strength and rupture resistance. Thus, a-SiC powder (0.Several substances with their cas registry numbers 409-21-2 and 12071-35-1 may be metioned in this study.5-1.0 m diam.) 95 and Y powder (1-100 m diam.) 5 mol% were mixed, molded, and hot-press sintered at 300 kg/cm2 and 20-40°/min to 2200° to give a SiC ceramic having 98.8% relative d., 67.2 kg/mm2 4-point bending strength, and 5.9 MN/m3/2 fracture toughness at 1400°. .
