Zawrah and Shaw [16] processed Al 93 Fe 3 Ti 2 Cr 2 alloy by mechanical alloying.Results showed that the hardness of Al 93 Fe 3 Ti 2 Cr 2 alloys was twice that of 6061-Al alloys after mechanical alloying. Shaw et al. [17] identified the effect on nanostructured aluminum alloy (Al 93 Fe 3 Ti 2 Cr 2) of the process-control agents …
Biochar is the solid residue left behind during the thermal conversion of biomass into fuel products. It has typically been considered a lower-value byproduct compared to the higher-valued syngas and bio-oil, and so most renewable energy research in this area focuses on maximizing those two products via high-temperature or 'fast' …
Hello guys, i need to mix Barium sulfate, magnesium (40 micron) and Sulfur together, but if i only use a fine mesh sieve there will still be baso4 and sulfur clumps as big as the mesh holes, no matter how often i work it through. I wondered if i could just put this into a simple ballmill (plastic...

With a series of merits, Prussian blue analogs (PBAs) have been considered as superior cathode materials for sodium-ion batteries (SIBs). Their commercialization, however, still suffers from inferior stability, considerable [Fe(CN) 6] defects and interstitial water in the framework, which are related to the rapid crystal …
If the color of produced material is important, the color as well as the material of the grinding media must be considered. If highly pure form of product is required, the grinding media must be selected such that it can be easily separated from the finished product (for example, steel dust produced from stainless steel media can be magnetically separated …
As a practical method of mechanochemical action, ball milling was first proposed by John Benjamin in 1970 18.It can usually cause particle deformation, lattice …

Expanded graphite (EG) was ball-milled in a high-energy planetary-type mill under air atmosphere. The products were characterized by X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). During the milling process (up to 100 h), the crystallite size (L c) of EG decreases gradually from 15.4 to 11.3 nm. Compared …
