以紫钨为原料,利用工业化生产技术制备纳米钨粉体。通过XRD、EDS、SEM、FESEM、DTA-TG和比表面及孔径分布分析仪对样品的物相、成分、形貌、热稳定性和比表面及孔结构进行表征。结果表明:通过降低还原温度、减缓推舟速度、减小装舟量和增大通氢流量等还原工艺条件可制备优质纳米W粉体。 Purple violet as raw material, the use of industrial production technology preparation of nano-tungsten powder. The phase, composition, morphology, thermal stability and surface area and pore structure of the samples were characterized by XRD, EDS, SEM, FESEM, DTA-TG and specific surface area and pore size distribution analyzer. The results show that high quality nano-W powder can be prepared by reducing the reduction temperature, slowing down the pusher speed, reducing the amount of loading the boat and increasing the hydrogen flow rate.
