人造金钢石的合成,以碳素为原料,合金为触媒。其晶体内部往往含有一定数量的触媒合金包裹体,使得人造金刚石具有磁性,亦导致其他物理、化学性能发生变化。研究结果表明,人造金刚石的磁性属铁磁性,其磁性强弱与混入晶体内部杂质元素的种类、含量紧密相关,与抗压强度、晶形完整中和粒度等均有一定关系。因此,人造金刚石的磁性是质量鉴定、产品分级及其合理应用的重要依据。 Synthetic synthetic diamond to carbon as raw material, alloy catalyst. The crystal interior often contains a certain amount of catalyst alloy inclusions, making the synthetic diamond magnetic, but also lead to other physical and chemical properties change. The results show that the magnetism of synthetic diamond belongs to the ferromagnetism. The magnetic strength of the synthetic diamond is closely related to the type and content of the impurity elements mixed in the crystal, and has some relations with the compressive strength, the complete neutralization grain size and so on. Therefore, the magnetism of synthetic diamond is an important basis for quality appraisal, product classification and its reasonable application.
