In this article, we have carried out the Ni based self fluxing alloy powder and studied the effect on the laser alloying of 45steel layer which contains different weight percentage of nano-SiC powders...
The relationship between surface properties and water vapor absorption performance was studied according to crystal structure and surface free energy of purified palygorskite. The results show that th...
Abstract: Hydrothermal syntheses were performed at various pH values and temperatures to induce variability in kaolinite defect density. Temperature of synthesis ranged from 200 to 240°C, for 21 d. In...
Abstract: Inverse gas chromatography (IGC) at zero surface coverage was used for determining the surface characteristics of a slate sample. Previously this sample had been characterized by means of X-...
The association between clay silicates, and iron and aluminium oxides has a major influence on the chemical and physical properties of soils. In this work the interaction of a kaolin substrate with ir...
To evaluate the importance of oxides to the surface chemistry of acid mineral soils, clay fractions were separated from a surface and subsurface horizon of an Inceptisol representative of many of the ...
Smectites exchanged to various degrees with mono- or biprotonated 1,4-diazobicyclo(2,2,2)- octane (Dabco) have a porous structure in which the organic molecule acts as a pillar.乭 Less Dabco2+ than Da...
The catalytic activity of sepiolite from Amboseli, Tanzania, for the dehydration and dehydrogenation of ethanol at 150°–300°C has been studied using a flow reactor. Both reactions occur, but the catal...
The adsorption of sodium, chloride, and phosphate ions by allophane, imogolite, and halloysite has been studied in relation to the surface structure of the mineral samples. The high adsorption of phos...
The catalytic activity of sepiolite from Amboseli, Tanzania, for the dehydration and dehydrogenation of ethanol at 150~176 has been studied using a flow reactor. Both reactions occur, but the catalyst...
Aluminum ions as well as hydroxide precipitates promote improved extraction of iron from kaolinites during leaching. Selective aggregation of ultrafine particles in kaolinites, seemingly induced by pr...
The migration of small cations into the empty octahedral sites of dioctahedral clays allows one to study the local effects in the trioctahedral structure and the consequences of the exchange capacity ...
Nitrogen surface areas and pore-size distribution curves of various chrysotiles have been measured using a continuous flow method. A model founded on a hexagonal close packing of fibers has been adjus...
