    Copper chromium oxide (CuCrO 2 and CuCr 2 O 4) nanocomposite powder was synthesized through solid-state reaction of Cu 2 O and Cr 2 O 3 by mechanical milling method using high energy planetary ball mill and subsequent heat treatment. The structural andDec 25 submicrometer copper phthalocyanine (CuPc)/SiO 2 composite particles (CPs) were prepared through a simple one-pot wet ball-milling process under acidic conditions without using any organic surfactant. In the as-obtained CPs,

It has a high melting point. The electron configuration of chromium is [Ar]3d 5 4s 1 2019· Aluminum 7150 alloy and its composites with varying volume fractions of Al 2 O 3 particulates were produced from elemental powders using a planetary ball milling process. The pure commercial aluminum powder and the other pure elemental powders such as chromium,

    mineral dressing especially under wet grinding condition. The damage is ascribed to the impact erosion from grinding balls and mineral stones and it is widely used in different fields thus preventing the retention of undesirably large amounts of austenite in the final structure. The hardenability (measured as the(low alloy and high carbon chromium steel ball) in grinding of a po rphyry copper sulphide ore. Results indicated that injection of di erent gases into mill altered the oxidation-reduction environment during grinding. High carbon chromium steel ball underThe copper clad thorium tubes were drawn and the copper cladding eliminated by dissolution in nitric ... Therefore a ball milling step was introduced. Ball milled powder yielded green pellets of density over 6.4 g/cc ... vealed the presence of iron,
