I see they sell so called high energy ball mills for making nanopowders, which is interesting to me, otherwise you need to do funny things to get nanodispersions. Are they legit? My understanding is that a ball mill typically has a so called critical angular rotation where it is effectively having the most balls in grind mode, and that this ...

Mg 2 SiO 4 nanopowders were prepared from MgO and SiO 2 mixtures by using a high energy ball milling method, combined with subsequent calcination at low temperatures. After milling for 30 h, pure phase Mg 2 SiO 4 nanopowders with an average grain size of nm were obtained at 850 °C, 300 °C lower than that required by a conventional solid state reaction process.

In this research, nearly spherical CuO nanopowders (NPs) were synthesized in a highenergy ballmilling method at room temperature for different milling times (20 and 40 h) at dry medium. The structure, particle size, purity and morphology of the resulting CuO NPs were characterized by Xray diffraction, inductively coupled plasma and scanning electron microscopy (SEM) techniques. The results ...

Planetary ball mills are the most popular mills used in scientific research for synthesizing MgH 2 nanopowders. In this type of mill, the ballmilling media have considerably high energy, because milling stock and balls come off the inner wall of the vial and the effective centrifugal force reaches up to 20 times gravitational acceleration ...

We present the process of synthesis and characterization of magnetitemaghemite nanoparticles by the ball milling method. The particles were synthesized in a planetary ball mill equipped with vials and balls of tempered steel, employing dry and wet conditions. For dry milling, we employed microstructured analyticalgrade hematite (αFe2O3), while for wet milling, we mixed hematite and ...
