2Synthesis of Nanoscale Shell-core Titania Coated Silica Particles in the Presence of Polyether Polyamine and the Phase Transition显示文摘The nanoscale titania coated silica was prepared via a two-step precipitating approach, where the nanoscale silica nuclei were first prepared by passing an aqueous solution of sodium silicate through an ion-exchange resin bed, then coated with the precipitation from hydrolyzed butyl titanate in an ethanol-hexane mixture at a low pH value in the presence of poly(ethylene oxide) polyamine salt(PPA) at a high temperature of 90 ℃. In the second-step precipitating process, the spontaneously precipitated titania shell on the silica nuclei was stabilized in the suspension solution with the help of the adsorption of PPA on the particles. A possible precipitating mechanism was suggested. Furthermore, the amorphous titania shell could undergo crystallization from the amorphous to the anatase structure at a high temperature of 650 ℃, and a further phase transition from the anatase to the rutile structure in the different sintering processes at a rising temperature of 750 ℃.HUA Feng-jun 1, SUN Jun 2, HONG Ke 2, GAO Lian 1 and YANG Yu-liang 1** 1.

3Preparation and Properties of Nano-TiO_2 Powders显示文摘This paper reports the preparation of nano-TiO2 (about 10 nm) powder by the method of precipitation. In detail, some breparation conditions were investigated in order to find out how to control the grain size and reduce the agglomeration of powders. Also, the reflex spectra of nano-scale powders with different grain size were studied. It tvas found that the wave length and width of reflex spectra are connected with the grain size of nano-TiO2Zhe SONG Qing LI and Lian GAO(State Key Lab. of High Performance Ceramics & Superfine Microstructure, Shanghai Institute of Ceramics,Chinese Acadmey of Sciences, Shanghai 200050, China) 1997Journal of Materials Science & Technology1997,13,4:3

17Preparation of Compound Ultrafine CeO2 by Wet-Solid-Phase Mechanochemical Modification显示文摘To satisfy practical requirements from industrial applications, an alternate route for synthesis compound ultrafine CeO2 powders by wet-solid-phase mechanochemical modification using industrial grade hydrated cerium carbonate as raw material was proposed.The effect of modifier reaction percentage, reaction time, calcining temperature and modifier amount on particle size, density, suspensibility, and hardness of compound CeO2 powder was investigated.The phase evolutions of preparation process were characterized by XRD.SEM micrograph of the final product shows that compound CeO2 powders obtained are well-dispersed, spherically-shaped, uniformly-sized and submicron-sized particles.The method is readily available in raw material, low in cost, simple in process, and has great potential for industrialization.The compound CeO2 powders of different physical properties can be synthesized by controlling the above-mentioned influence factors in preparation process.Gu Ziyin Chen Weifan(China National Special Superfine Powder Engineering Research Center, Nanjing University of Science & Technology, Nanjing 10094, China) Hu Pinggui Li Yongxiu 2004Journal of Rare Earths2004,22,z1:1

19Estimation of Solid Phase Relationship in the Al_2O_3-SiO_2-Re_2O_3 Systems显示文摘Nine limiting binaries of A12O3-SiO2- Re2O3 (Re=Nd, Sm, Gd and La) system are assessed. The binary diagrams or experimental information from Toropov, Mizuno, Aramaki, Bondar, Rolin and Coutures are optimized with the substitutional model of Kaufman and Nesor and the approximate formula of fusion free energy for rare earth element oxides of Wu and Pelton. The extracted Gibbs free energies of pure solid oxides and stoichiometric phases and the solution parameters are used to estimate the corresponding binaries, and a series of isothermal sections of four ternaries Al2O,-SiO2-Nd2O3, A12O3-SiO2-SiO2O3 , A12O3-SiO2-Gd2O3 and A12O3-SiO2-La2O3. In the Al2O3-SiO2-Gd2O3 system samples as fired at exact temperature with different compositions were analyzed by x-ray diffractometer and the detected results are fitted with the calculation of isothermal sections.Li Lin, Sun Weiying, Wang PeEling, Tang Zhujun 1.School of Materials Science & Engineering, Shanghai University, Shanghai 200072, China 2.State Key Lab of High Performance Ceramics and Superfine Microstructure, Shanghai Institute of Ceramics, Chinese Ac 2000Journal of Shanghai Jiaotong university(Science)2000,5,1:0
20Blue-shift of Nano-Y_2O_3 : Eu^(3+) Emission Spectra Excited by X-ray显示文摘Nano-Y2O3:Eu3+ powder was prepared by the homogeneous precipitation. With controlling the conditions of the reaction, nano powders with different grain size were obtained. It is found that the blue-shift phenomena exist in the nano-Y2O3:Eu3+ emission spectra excited by X-ray. The wave lengths of the peak (5D0→7F2) are related with the grain size of theQiang LI Lian GAO and Dongsheng YAN(State Key Lab. of High Performance Ceramics & Superfine Microstructure, Shanghai Institute of Ceramics,Chinese Academy of Sciences, Shanghai 200050, China) 1997Journal of Materials Science & Technology1997,13,4:0
