Scale-Up of Nanocorundum Synthesis by Mechanochemical Dehydration of Boehmite.

ABSTRACT: This work presents the scale-up of room-temperature mechanochemical synthesis of nanocorundum (high-surface-area α-Al₂O₃) from boehmite (γ-AlOOH). This transformation on the 1 g scale using a laboratory shaker mill had previously been reported. High-energy Simoloyer ball mills equipped with milling chambers of sizes ranging from 1 to 20 L were used to scale up the mechanochemical nanocorundum synthesis to the 50 g to 1 kg scale, which paves the way to further increase batch size. Milling chambers made of steel and lined with silicon nitride (Si₃N₄) and milling balls made of steel, zirconia (ZrO₂), and silicon nitride (Si₃N₄) were investigated to address the abrasion problem, leading to contamination of the alumina
