High-surface-area corundum by mechanochemically induced ...

This finding was substantiated by ball milling of boehmite in the planetary mill using steel, sintered corundum, or zirconia milling jars and media. The higher impact and friction forces involved in planetary milling led to the direct formation of α-Al 2 O 3 (see fig. S6). Notably, milling equipment made of corundum can also be used to exclude ...
