, energy-dispersive spectrometry, and X-ray powder diffraction. Results show that Na effectively inhibited S catalysis during carbon–air/CO2 reactions, and S inhibited the catalysis of Na during carbon... and Al in Na3AlF6 can be seen as harmless and inactive during coke–air/CO2 reactions, Na3AlF6 is selected as the only source of Na for the study on the mechanism of mutual inhibition between S and Na......
product decreased, indicating that both MgO and La2O3 may take part in the reactions in the electrolyte. When the same mass of the oxide was added, compared with La2O3, MgO had a more pronounced effect... effect of MgO on the electrolysis, probably due to the complex reactions of the La compounds in the electrolyte. Key words: Mg-La alloy; molten salt; electrolysis; oxide; fluoride; current efficiency 1......
were always opposite because of the competitive reactions of oxidation and calcification between vanadium and chromium with Ca O.Moreover,Ca O was more likely to combine with vanadium,as further... could be used as a new raw material for the extraction of chromium.Furthermore,the oxidation and calcification reactions of the spinel phases occurred at 592and 630°C for n(Ca O)/n(V2O5)ratios of 0.5......

The reduction reactions of the graphite-laterite mixtures... characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indi-cate that the reduction reactions proceed more completely at higher temperatures. The growth......

are related to the diffusion and interfacial reactions. A decrease of impedance magnitude with time was observed in EIS measurements concurrently with water absorption bands shifting towards lower wavenumber.../copper interface in a humid atmosphere. The interfacial ion transport process is controlled by the interfacial electrochemical reactions at the cathodic delamination front and the estimated average......
carbochlorination. These reactions were studied in laboratory experiments as well as additional reactions, which were needed for the main chemicals recycling: Cl2, ZnI2→Zn, CaCl2→CaI2. XRD and SEM methods... transforms the heat energy of combustion into electricity without Carnot limitations. 2 Brief review of known methods for aluminum reduction Metallurgy of aluminum has been given rise in the first part......
; 文献标志码:A Diffusion of Si in interfacial reactions between TiAl castings and ceramic moulds JIA Yi1,2, XIAO Shu-long1,2, XU Li-juan2, TIAN Jing2, CHEN Yu-yong1,2 (1. National Key Laboratory..., Harbin 150001, China) Abstract: The interfacial reactions between TiAl castings and ceramic moulds were investigated. The reaction interface between two kinds of alloys as Ti-46Al and Ti-46Al-7Nb......
