using inductively coupled plasma (ICP). The characterization of the solid samples was done by X-ray diffractometry and scanning electron microscopy (SEM). 3 Results and discussion 3.1 Effect... as well as hematite. With the mass ratio of acid to ore increasing, the main phase in the product is Fe2(SO4)3 that can be easily dissolved with nickel sulfate in the following water leaching. Fig.5 X......
at a potential of 0.05 V below the steady open-circuit potential(OCP) with a sweep rate of 5 mV/s to measure the potentio-dynamic anodic polarization curves in reference to a saturated calomel electrode(SCE). 3... and Si. 3) Both alloy 1 and alloy 2 exhibit excellent corrosion properties in NaOH solution characterized by their similar potentio-dynamic anodic polarization curves. This is ascribed to the formation......
stress was selected, the frequency sweeps were performed with a frequency range of 0.1-25 Hz and temperature sweeps with temperature ranging from 15 ℃ to 70 ℃. 3 Results and discussion 3.1 Effect... viscosity. The flow index of the system is found to be less than 1 as shown by typical pseudoplastic fluid. 3) The viscoelastic properties can also be affected by polycarbonates composition......
at that temperature for a reasonable time to eliminate the effect of the thermal history. A new solution was chosen for each new test in order to avoid the memory effects. 3 Results and discussion 3.1... not to be constant, but it has a value between 0 and 1[6-14]. On the other hand, in the theoretical field, MARTIN et al[3-4] predicted that n is between 2/3 and 1. Therefore, it seems......
, China). Bitumen was first heated until it became a well fluid at around 150 ℃ in an iron container. Then 3% OMMT was added into bitumen, and the mixtures were blended at ..., such as G*, δ, G*/sin δ and G*sin δ. 3 Results and discussion 3.1 Effect of montmorillonite on dynamic rheological properties of bitumen Dynamic shear rheological tests involve the application......
