Preparation of natural pyrite nanoparticles by high energy ...
· In the present study pyrite nanoparticles were prepared by high energy mechanical ball milling utilizing a planetary ball mill. Various pyrite samples were produced by changing the milling time from 2 h to 6 h, in the constant milling speed of 320 diffraction (XRD), scanning electron microscopy (SEM) linked with energy dispersive Xray (EDX), Fourier transform infrared spectroscopy ...
