【摘要】 选取相成分单一的氢钨青铜(H_0.33WO₃)、铵钨青铜(（NH₄）_0.5WO₃)和紫钨(WO_2.72)作为原料,研究钨原料对制取超细钨粉的影响;对氧化钨原料和超细钨粉的粒度测量方法作了比较,研究结果表明:紫钨由于有着特殊的结构,其制得的钨粉细而均匀,分散性好,是适合于做微晶硬质合金的原料;对于氧化钨原料的粒度（伪同晶颗粒尺寸,即二次颗粒）测量,推荐使用激光衍射法;对于超细钨粉粒度（一次颗粒）的炉前测量,BET法测球形相当径相当理想。更多还原

【Abstract】 In this article three kinds of tungsten oxide materials of hydrogen tungsten bronze (H_0.33 WO₃ ), ammonium tungsten bronze(（NH₄）_0.5WO₃ ), violent tungsten-γ oxide (WO_2.72) were selected to study the influence of raw materials on producing ultrafine and homogenous tungsten powder. Researching results show that because of the special pore structure of WO_2.72 particles, the homogenous and ultrafine tungsten powder derived from WO_2.72 has loose structure which is more suitable for the micrograin hard metals than the powders from the other TBO materials selected in this study. The authors suggest that a suitable methed for evaluating particle size of tungsten blue oxide is laser diffraction and the optimum in - line measurement method for particle size of ultrafine tungsten powder is the BET method for equivalent spherical diameter.更多还原
