Effect of particle size on the polycrystalline CeB6 cathode prepared by spark plasma sintering包黎红,张久兴,周身林Key Laboratory of Advanced Functional Materials, Ministry of Education, College of Materials... by using the spark plasma sintering (SPS) method in an oxygen free system. The starting precursor nanopowders with an average grain size of 50 nm were prepared by high-energy ball milling. The ball......
is evenly distributed on the MMC with an average particle size of 15μm. The high percentage of SiC particle reinforced phase is obtained on the layer of the specimen. Fig.2 Microstructure of laser...Cavitation-erosion mechanism of laser cladded SiC particle reinforced metal matrix composite ZHANG Chun-hua(张春华)1, 2, 3, ZHANG Song(张 松)1, YANG Hong-gang(杨洪刚)1, ZHU Sheng-long(朱圣龙)2, MAN Hau......

School... method. The analyses include not only the relationship between the parameters and the particle size, but also the effect of parameters n and b on the particle size distribution. And the conclusion......
Effect of particle size and agglomeration of TiO2 on synthesis and electrochemical properties of Li4Ti5O12 WU Le(伍乐), KAN Su-rong(阚素荣)?, LU Shi-gang(卢世刚), ZHANG Xiang-jun(张向军), JIN Wei-hua(金维华... phase during the solid-state synthesis process of Li4Ti5O12. It is supposed that the particle size distribution of Li4Ti5O12 powder may mainly depend on the grain size of TiO2. In this study......
; 文献标志码:A 文章编号:1672-7207(2011)05-1238-05 Influences of proportion of dual particle size on densification... by copper infiltration to fabricate W-10Cu composite. The effects of the particle size ratio on the properties of sintering density, hardness, conductivity and microstructure of the composite were......
of the feature size (0.05 mm by the year 2010), the limited size of particles will be rigorous inducing circuit imperfect. The particle size larger than 0.12 μm should be less than 500 per square meter [4... that all the amounts of the particles which size is larger than 0.2 μm are less than 10 per wafer and reach the SEMI standard. Table 1 Amount and size of particle on wafer after cleaning 3.4......

(2021) 28: 633-647 DOI: https://doi.org/10.1007/s11771-021-4633-x Effect of CuO and SnO2 particle size on hot extrusion deformation of AgCuOSnO2: Finite element simulation... calculation. In terms of the combination of finite element analysis and experiment, the effect of particle size of CuO and SnO2 on the stress, strain and microstructure of AgCuOSnO2 composite during hot......
is contributive for particle deposition, so it provides an efficient approach to remove particles, especially with small size, e.g., PM2.5. Moreover, the convex wall cavity leads to a larger increment of than... J. Cent. South Univ. (2018) 25: 2601-2614 DOI: https://doi.org/10.1007/s11771-018-3939-9 Particle deposition in ventilation duct with convex or concave wall cavity WANG Fei-fei(王飞飞)1, ZHANG En-shi......
, feedstock particle size and size distribution, amount of feedstock and Cl2 and CO flow rates on the conversion were systematically investigated. A gradual increase in chlorination temperature led to monotonous increase of conversion rate. Conversion decreased with increased particle size of feedstock. An increase in loaded feedstock led to a decrease in reaction conversion. A model was proposed to predict......
