  • Remediation of heavy metals contaminated soils by ball

    In the present work the use of ball milling reactors for the remediation of lead contaminated soils was investigated. Lead immobilization was achieved without the use of additional reactants but only through the exploitation of weak transformations induced on the treated soil by mechanical loads taking place during collisions among milling media.

  • Synthesis of lead-borate glasses using high energy ball

    High energy ball milling (attritor) was performed to synthesize amorphous PbO-25 mol B 2 O 3 at room temperature. The milled samples were subsequently melted with a less cost-effective way in contrast to other conversional methods. The milled samples were examined by X-ray diffraction and Fourier transform infrared spectroscopy to investigate their amorphization.
