Abstract

Abstract

The effects of high energy shear broken time on the settlement curve, mean grain size, BET surface area and apparent density of WO₃ and W powders were studied. The powders after and before being broken were observed directly by TEM and SEM. The results showed that by the new-type high energy shear milling micrometer WO₃ powder can be broken, and bridged particles in ultrafine W powder can be cracked, with the apparent density of W and WO₃ powders doubling, but without much influence on their specific surface area.
