09.14.2021. By Arvin Donley. It's been said the first flour miller was the first person who chewed on a wheat kernel. While the details of that milestone will never be known, we do know the transition to using millstones instead of molars to extract flour occurred around 6000 BC, and it remained the primary flour-making method for many centuries.

5 min in a ball mill. The mixed powders were then poured and cold-pressed at a pressure of ∼263 MPa in a ∼12.7 mm steel die (Model EQ-Die-06D-B, MTI Corporation, Richmond, CA). The cold-pressed samples were then demolded to form compacts. The compacted samples were then pyrolyzed in a tube furnace for 1 h with flowing Ar at 300, 500, 700 ...
