| Abstract: |
To solve the mirofiltration problem in harsh environments, the porous Nickel–Copper (Ni–Cu) alloy is fabricated by powder metallurgy. Homogenous skeleton and abundant interconnected pores microstructure are found in the as-sintered porous Ni–Cu alloy. Meanwhile, it maintains an adequate mechanical strength under high temperature up to 900 °C. Corrosion kinetics indicates that the corrosion resistance of porous Ni–Cu is superior than porous nickel in the same concentration of hydrofluoric acid. Compared with conventional phosphorus slag purification practices, the described porous Ni–Cu filters enable the superior-yield of phosphorus effectively and have the potential to decrease the energy consumption and simultaneously ensure an environmental friendly process in phosphorus industry.
