2017. 9. 1. Zirconium oxide (ZrO 2) vials and ZrO 2 balls were coated by tungsten layer to avoid the contamination on the powder. Analysis of ZrO 2 ball surface and tungsten powder after ball milling was performed and the results (not shown here) show that the status of tungsten coating is as good as initial coating and no zirconium contaminates the milled tungsten powder.
2018. 11. 1. Under the impact force and shear force exerted by the grinding balls and the vessel's wall, the tungsten powder experiences compressional deformation during ball milling, at the same time, two or more tungsten powder particles weld together to form one much larger particle, and the tungsten powder appears welding due to the Van der Waals force as the tungsten atoms become close.
