Dense 3YZrO2 composite ceramics were prepared by using 3YZrO2 nanopowders as the raw materials, via the process of ball milling, granulating, molding and investigated the microstructure, surface morphologies, the mechanical property, the density and linear shrinkage rate of the sintered ceramics and the effect of the ball milling technics and the sintering technics on the
Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multilayered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,Ndimethylformamide (DMF) and exfoliated by shearforcedominated ball milling carried out in a planetary mill. After highspeed centrifugation, irregular shaped single and fewlayer graphene sheets (3 layers

For all nanocrystalline materials prepared by highenergy ball milling synthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for highenergy ball milling. However, using optimized milling speed and milling time may
