WO3粉在高速层间剪切条件下的颗粒破碎特征

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

    摘要
  • 摘要: 研究了WO3粉和W粉的剪切破碎时间对WO3粉和W粉的沉降曲线、平均粒度、BET比表面及松装密度的影响.用TEM和SEM对剪切破碎前后的粉末进行了直接观察.结果表明:新型剪切破碎机能有效地粉碎微米级WO3等脆性粉末,同时可以破坏超细W粉中的桥接团粒,使W粉和WO3粉的松装密度增加1倍以上,但对比表面积影响不大.

     

    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.
