). It was of cubic system when the sample was synthesized at a low temperature and the particle size was about 30 nm. The results showed that adding surfactants was useful to improve the powder......
(AAS). Different parameters such as the concentration of surfactants, chelating agent and salt, sample pH, equilibration temperature and time, centrifugation time and rates, and the effect of foreign......
="ChDivSummary" name="ChDivSummary">ZnO nanosheets and nanoflakes were grown on alumina particles in the absence of surfactants via heterogeneous precipitation using urea,zinc acetate and bayerite......
powders were prepared by intermittent electrodeposition. The influence of process parameters such as current density, single deposition pulse, p H value and surfactants on the formation of WC/Co......
sample magnetometer(VSM).Some key reaction parameters,such as the reaction time,reaction temperature and surfactants,have important influence on the morphology of the final products.XRD pattern indicated......

, the surfactants and the degree of agitation, the optimal coprecipitation conditions were determined. Varistors prepared by coprecipitation chemical method display electrical properties leak current 50 μA......
obtained with size in a tunable range of 4- 15 nm and their morphologies could be tuned from spherical to triangle-shaped by varying the surfactants. The phase structure, morphology... reaction of metal acetylacetonate with 1,2-hexadicanediol in the presence of surfactants [15]. Recently, ADIREDDY et al obtained monodisperse ferrite nanocrystals by the thermolysis of transition-metal......
文献标识码:A Influences of surfactants on wettability and floating property of bronze powders FENG La-jun, XU Da-peng, LEI A-li (School of Materials Science and Engineering..., floating property and gloss of the coated bronze powders were measured, and the influence mechanisms of the surfactants on the wettability and floating property of the bronze powders were analyzed......
concentration but big and tight aggregation at a high concentration is presented. At pH=7 alkyl quarterly amine salt CTAB has the best hydrophobic aggregation among three cationic surfactants, namely... with cationic surfactants[15-18]. In this work, the hydrophobic aggregation of kaolinite was investigated through zeta potential measurement, SEM observation and sedimentation test. 2 Experimental 2.1......
