Lithium niobate (LiNbO3, LN) nanocrystals were prepared by ballmilling of the crucible residue of a Czochralski grown congruent single crystal, using a Spex 8000 Mixer Mill with different types of vials (stainless steel, alumina, tungsten carbide) and various milling parameters. Dynamic light scattering and powder Xray diffraction were used to determine the achieved particle and grain sizes ...
The above milling experiment was carried out at Fritsch Pulverisette 6 planetary highenergy ball milling system in the air, with room temperatures for different times. A 250 ml stainless steel carbide vial with 10 stain less steel balls, along with a diameter of 20 mm, was used as a milling medium. The milling speed was set at 370 rpm.

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
The aim of this study is to prepare CuO–CeO2 composite by means of mechanical milling and to investigate its characteristics as a catalyst. The structural and morphological features of milled sampl...
Nov 15, 2005· The evolution of particle size of the BT powders, after different milling times in a high energy ball milling (SPEX 8000 mixer mill) were monitored by SEMimage analysis and XRD. BTpowder in the submicrometric size (~280nm) prepared after 120 min of milling were used to fabricate the targets by pressing (138 MPa) and sintering (950°C).
Highenergy ball milling was used to prepare the nanocrystalline powder; it was followed by consolidation using spark plasma sintering. During highenergy ball milling, particles are subjected to repeated flattening, cold welding, fracturing and rewelding. When two milling balls collide, a certain amount of powder is trapped
