  • Synthesis of HgPb2 assisted by high energy ball milling

    AbstractThe aim of this work was to demonstrate that high energy ball milling process can induce the formation of HgPb2 compound. It has been found mechanical milling is a very effective low cost and simple technique to produce this material without surfactant and further annealing. The powders after milling for various durations were characterized by X-ray powder diffraction.

  • Structural and Kinetic Hydrogen Sorption Properties of Zr0

    The effects of ball milling on the hydrogen sorption kinetics and microstructure of Zr 0.8 Ti 0.2 Co have been systematically studied. Kinetic measurements show that the hydrogenation rate and amount of Zr 0.8 Ti 0.2 Co decrease with increasing the ball milling time. However the dehydrogenation rate accelerates as the ball milling time increases.

    Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ball-milling. A standard way of modifying the ball mass is to change the size of the ball made of the same material. In this case however a change in mass is accompanied by a simul Editor s Collection Mechanochemistry The Solid State of Pharmaceuticals
