Diffusion Mechanisms in Amorphisation by S-s Reaction
نویسنده
چکیده
In SSAR, diffusion through the growing thickness of amorphous material separating the reacting metals is likely to be rate-determining for the speed of reaction. Accordingly, understanding of diffusion rates helps in interpreting reaction kinetics. This presentation outlines the principal generalizations now established for diffusion in metallic glasses, including effectsof atom sizes, activation energies, and .the effect of relaxing the glass structure on diffusion. Evidence about the rate of diffusion during SSAR is outlined.

Adsorption Mechanisms of Cadmium onto Pillared Clays and Chalcogenides
Interactions between Cd, pillared clays and chalcogenedies have been studied using nanomineralogical experiments. XRD, DSC and chemical analysis. The synchrotron-based X-ray absorption spectroscopy (XAS) was applied to characterize the reaction phases. The mean bond lengths between, Cd-S, Fe-S, Sb-S, Cd-Cd (in chalcogenedies), Al-Cd, Cd-Ti, and Fe-Cd, (in pillared clays) were determined by XAS ...
متن کاملKinetics of Sphalerite Leaching by Sodium Nitrate in Sulfuric Acid
In the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. The effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (S/L) ratio were analyzed. The dissolution rate increased with increase in the sulfuric acid an...
متن کاملNumerical Study on the Reaction Cum Diffusion Process in a Spherical Biocatalyst
In chemical engineering, several processes are represented by singular boundary value problems. In general, classical numerical methods fail to produce good approximations for the singular boundary value problems. In this paper, Chebyshev finite difference (ChFD) method and DTM-Pad´e method, which is a combination of differential transform method (DTM) and Pad´e approximant, are applied for sol...
متن کاملEFFECT OF Si ANTIOXIDANT ON THE RATE OF OXIDATION OF CARBON IN MgO- C REFRACTORY
Progressive conversion/shrinking core (PC-SC) models of constant-size cylinders were exploited to interpret the decarburization reactions of MgO-C-Si bricks heated up under blown air. Chemical adsorption/solid (or pore) diffusion mechanisms governed the reaction rate. With 5% silicon, chemical adsorption vanished at 1000 and 1100°C. The oxidation rate lowered then with temperature. This was due...

In this work, the thermal reaction of aluminum (Al) and nickel oxide (NiO) was investigated by molecular dynamics simulations. Some effective features of reaction such as reaction temperature, the reaction mechanism, and diffusion rate of oxygen into aluminum structure were studied. ReaxFF force field was performed to study the Al/NiO thermite reaction behavior at five different temperatures (5...
