摘要:
以工业化生产设备制备纳米碳化钨粉,采用X射线衍射谱(XRD)、比表面积法(BET)、冷场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)、激光动态光散射仪对样品的物相、粒度及其分布进行表征,探讨其测量原理.实验结果表明:纳米碳化钨粉的平均颗粒尺寸为90 nm,大多数近似球形,也有一部分呈多角形.为了能更准确地测量纳米碳化钨粉颗粒的粒径,分散剂中的样品要有较好的分散,才能破坏团聚体,同时纳米碳化钨粉颗粒的形状对激光动态光散射仪的测量结果具有重要的影响.
Abstract:
Nanocrystalline tungsten carbide(nano-WC) powder was prepared on the basis of the industrialized production equipment.Methods of X-ray diffraction,specific surface area,FESEM,TEM,and laser particle analyzer of dynamic light scattering were applied to test the phase,particle size and its distribution of nano-WC powder.Discussion was made for the testing principle.The results indicate the average particle size of nano-WC is 90 nm and most of the particles are spherical shape,but few are the shape of the polygon.In order to more accurately measure particle size of nano-WC powder,the sample should have good dispersion to avoid aggregation.The shape of nano-WC powder also have important influence on measurement of particle analyzer of dynamic light scattering.
