| 摘 要： | 探讨了含稀土合金粉末对合成金刚石的影响.采用加入少量稀土的NiFe-C作为原料,构成"NiFe-RE-C"粉末材料,再对该粉末一体化芯坯进行活化处理.在超高压、高温的条件下,经一定的工艺流程合成了高品级金刚石.采用该方法的显著特点是提高了金刚石的粗粒度百分比,且生产出的金刚石样品质量高,具有很好的冲击韧性.

| Abstract: | A new method of synthesizing diamond with the rare earths powder is reported in this paper.The diamonds are produced by using the graphite-NiFe-alloy powder catalyst with small amount rare earths under superhigh pressure and temperature. The obvious characteristic is that the percentage of coarse-grained diamond can be raised and the size is concentrated.The quantity is high in each sample of diamond.And the impact toughness of the synthetic diamond is very excellent. |
