Broken characteristic of WO₃ particles under the condition of high-speed interlayer shear milling

Materials and Engineering School, University of Science and Technology Beijing, Beijing 100083, China

摘要: 研究了WO₃粉和W粉的剪切破碎時間對WO₃粉和W粉的沉降曲線、平均粒度、BET比表面及松裝密度的影響.用TEM和SEM對剪切破碎前后的粉末進行了直接觀察.結果表明:新型剪切破碎機能有效地粉碎微米級WO₃等脆性粉末,同時可以破壞超細W粉中的橋接團粒,使W粉和WO₃粉的松裝密度增加1倍以上,但對比表面積影響不大.

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.
