029, China) Abstract: Nanotitaniapowderwithparticlesizeof20 ~ 30nmwaspreparedbyemployinganovelhigh-gravityrotatingpackedbed (RPB) reactorandneutralizationhydrolysisprocess,tory burch flats sale, withTiChandammoniagasasrawmaterials. ExperimentalresultsindicatedthatthehgihgravityenvironmentinRPBfavoredthesynthesisofsphericalnanotitaniawithnarrowsizedistributionandgooddisper'sion. Theoptimumconditionsofpreparingnanotitaniabyahigh-gravitymethodweredeterminedasTiChsolutionconcentrationof0.5mol / L, RPBrotatingspeedof1200 ~ 1600r/min,puma futrue cat, finalpHof7 ~ 9andreactiontemperatureof30 ℃. Thismethodexhibitedthemeritsofsimpleness, higheffciencyandnounfavorablescaling-upeffects.

X-raydiffractionresultshowedthatSrTiO3/Y1Ba2Cu3O (STO / YBCO) werewell-crystallizedandhigh-lyc-axisoriented. AFMimagesindicatedthatsurfacesofSrTi () 3/YlBa2Cu3O (STO / YBCO) weresmoothandhomogeneous. Tunabilitygreaterthan38% wasachievablewiththebiasfieldof53.6kV/cm. ThedielectricdissipationofSTOfilmslowerthan10_. wasachievedat100kHzaround77K.
