was added dropwise to the Ca+Zn solution, and the pH of the mixture was maintained at 10. The reaction mixture was then refluxed under microwave radiation (Samsung- MW71B, 800 W, 2.45 GHz) for 10 min..., and the graphite rod was used as counter electrode. The samples were immersed in the SBF for 1 h prior to the potentiodynamic polarization (PDP) test to establish the open-circuit potential......
2.2.1 Flotation tests 10 g chalcocite and 90 g pyrite were mixed with 100 mL water and ground to 80 wt.% particles less than 106 μm in a rod mill for 4.8 min using stainless steel grinding media... flotation [J].

, and the balance copper in wt. %; detected by ICP-OES) with the particle size less than 150 μm were prepared using gas (N2) atomization method. Cu-15Ni-8Sn alloy rod was fabricated by hot isostatic pressing (HIP.... The wear rate was calculated by an equation of w=△m/ρL, where w is the wear rate (mm3/mm), △m is the wear mass loss (g), ρ is the density of the specimen (g/cm3) and L is the total sliding distance (m......
. A representative sample weighing 15 g obtained from each of the reduced products was wet ground in an XMB (d65 min × 76 mm) rod mill at a pulp density of 70 wt.%, constituting 85% passing 74 μm. The slurry... in the following three formulas: R=w(CaO+MgO)/ w(SiO2+Al2O3) is called the quaternary slag basicity, also called the total slag basicity; R=w(CaO+MgO)/ w(SiO2) is the ternary slag basicity; R=w(CaO)/ w(SiO2......

The HPDC die includes a rod creep specimen with a gauge length of 100 mm and a cross section diameter of 10 mm, and a flat tensile specimen with 2.2 mm in thickness, 40.... As displayed in Figs. 5(a) and (b), the Si particles exhibit an elongated rod-like morphology with sharp edges in both PMC and HPDC alloys. The Si particles become larger and more spherical without sharp edges......
