SMALL-ANGLE X-RAY SCATTERING ANALYSIS OF PARTICLE SIZE DISTRIBUTION OF COLLOIDAL SiO2 SoL陈岩,魏铭鉴摘 要:<正> For the determination of particle size... Distribution Function were adopted.The results onparticle size distribution showed that the two procedures of intensity analysis led to a quite coincidentconclusion.Also the results have a good agreement......
with the apparent activation energy of 80.175 kJ/mol. Moreover, the oxidation rate is closely related to particle size of the concentrate. The smaller the particle size is, the larger the oxidation rate is. Key words: molybdenite; oxidation; roasting; kinetics; particle size 1 Introduction Molybdenum is widely used in materials and chemical industry [1,2]. Molybdenite is the main mineral of molybdenum......
