| 摘 要： | 用碱熔、酸洗、碳化处理制得的微晶碳做助磨剂,球磨金属镁3 h,制得储氢材料70Mg30C。用扫描电镜和原子力显微镜观测可见,颗粒的平均粒径约为100 nm,颗粒大小主要分布在50~100 nm之间,而透射电镜观测的颗粒大小主要集中在50 nm左右。扫描电镜图的粒度分布近似为对数正态分布,粒度分布范围为25~260 nm。

| Abstract: | Hydrogen storage material 70Mg30C was prepared by milling of magnesium under hydrogen atmosphere for 3 h with crystallitic carbon, which was prepared from anthracite coal by demineralization and carbonization, as milling aid. The particle size was in the range of 50-100 nm from SEM and AFM analysis and the average particle size was about 100 rim. TEM analysis showed that the particles were mainly about 50 nm. The particle size distribution of the SEM image is approximately a logarithmic normal distribution and the particle size range is 25-260 rim. |
