| 1 | PREPARATION OF ULTRAFINE METAL PARTICLES BY COMBINED METHOD γ-RAY RADIATION—HYDROTHERMAL CRYSTALLIZATION显示文摘The γ-ray radiation technique combined with hydrothermal crystallization was firstlyused to prepare ultrafine metallic particles of An,Cu and Au-Cu alloy.Particle sizefor Au in average is about 10 nm.The morphologies were observed by TEM.Thenucleation mechanism of metal particles and their stability are discussed. | CHEN Zuyao CHEN Bo QIAN Yitai ZHANG Manwei YANG Li FAN Chenggao University of Science and Technology of China,Hefei,China | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，11： | 13 |

| 4 | HIGH-Tc SUPERCONDUCTING PROPERTIES OF YBa_(2)Cu_(3-x)Sn_(x)O_(7-y) SYSTEM显示文摘The effect of Sn concentration on the superconducting properties and structure of YBa_(2)Cu_(3-x)Sn_(x)O_(7-y) system were systematically investigated.The zero resistance temperature was found to be above 90K as z ranges from 0 to 1.1.For x>1.3,the system exhibited no superconducting properties at liquid nitrogen temperature.The results of X-ray diffraction showed a regular pattern of mixed structures of 123 phase and a new phase in the system with the increase of Sn concentration.TEM analysis suggested that the new phase might be BaSnO3 with deformed perovskite structure and about 6% of Cu were substituted by Sn in the 123 phase at x=1.0.It is therefore likely that the new phase modulates the structure of 123 phase and stabilize the 123 phase.Although the Sn atoms enter 123 phase and occupy the Cu sites in the Cu-O chain and break the chain,the system remains with Tc>90K.Consequently,the Cu-O chain plays a less important role in the high-Tc superconductivity. | WANG Yuxia RUAN Yaozhong TAN Yudong WANG Xiaozhong ZHOU Guien FAN Chenggao ZHANG Yuheng | 1990 | Chinese Physics Letters1990，7，7： | 0 |
| 5 | Intercalation Reaction of Bi_(2)(Sr,Nd)_(2)CuO_(y) Bi_(2)Sr_(2)(Ca,Gd)Cu_(2)O_(y) and Related Compounds With Iodine显示文摘With iodine vapour treatment of various single crystals of Bi-Sr-Ca-Ln(Rare earth element)-Cu-O system,the stage-1 iodine intercalation compounds of Bi_(2)(Sr,Nd)_(2)CuO_(y) (2201),Bi_(2)Sr_(2)(Ca,Gd)Cu_(2)O_(y) or Bi_(2)Sr_(2)CaCu_(2)O_(y)(2212)and Big SrCaO14 have been prepared.x-ray difraction and transmission electron microscope analysis indicate that iodine layer of thickness 3.2-3.5A is formed between two Bi_(2)-O_(2) layers. | CHEN Zuyao GU Zhengtian QIAN Yitai WANG Xiqin HUANG Yunlan FAN Chenggao ZHOU Guien | 1991 | Chinese Physics Letters1991，8，11： | 0 |
