Centre for Material and Fibre Innovation, Deakin University, Geelong Vic 3217, Australia Received 10 April 2006; accepted 25 April 2006 Abstract: Hydroxyapatite/titania... for orthopaedic applications Key words: Ti scaffolds; sol-gel method; Hydroxyapatite; Titania; HA/TiO2 coatings; simulated body fluid 1 Introduction Bone injuries and failures often require......
temperatures ranging from 580 ℃ to 800 ℃, the aperture of coating is 0.5-1.0 μm and titania nanowires with approximately diameter of 100 nm and the micro-metric length are embedded in as-obtained.... Key words: hybrid sol-gel; apatite; titania; honeycomb-like coating; single crystal silicon 单晶硅作为一种重要的半导体材料,已被广泛地应用于生物学和医学研究与应用领域中,目前,单晶硅在生物芯片,生物传感器和微电子机械系统等微型器件中都有重要的应用[1-4].但晶体硅是一种生物惰性材料,被植入人体后,会导致......
%, the O2 evolution speeds are 130.4 and 69.6 umol/(L?h) under UV irradiation and visible radiation, which are 14.6% and 12.1% higher than those before doping, respectively. Key words: rutile titania......
A Study on the Thermal Stability of La2O3-TiO2 Supports郑柏存,汪仁摘 要:<正> In this paper,various techniques including BET,XRD,SEM and XPS were used to study the sintering ofpure and La2O3-doped titania.The experimental results show that sintering of titania proceeds via volume diffu-sion.Adding of lanthanum oxide decreases the rate of sintering......
University, Changsha 410083, China摘 要:Monodisperse titania glycolate submicrospheres were synthesized by a modified sol-gel route, in which ultrasonic treatment...-ray diffraction (XRD), and scanning electron microscopy (SEM). The results indicate that the as-prepared products are titania glycolate submicrospheres with diameters of 230-330 nm. The average particle......
the reflectance of white dielectrics,titania has been used commercially as a filler in a glass matrix despite its high dielectric constant.However,calcite has some advantages over titania as a filler,such as its low dielectric constant and the low price of the raw material.We fabricated composites with titania and calcite as the filler in a B2O3-ZnO-BaO-P2O5 (BZBP) glass matrix and investigated......
Engineering摘 要:<正>Two kinds of different structured alumina-titania composite powders were used to prepare alumina matrix ceramics by microwave sintering.One was powder mixture of alumina and titania at a micron-submicron level,in which fused-and-crushed alumina particles(micrometers) was clad with submicron-sized titania.The other was powder mixture......
