摘　　要：本文对ＣＨＳ－３触媒材料的制备及应用进行了研究，讨论了合成工艺对触媒合成效果的影响，考察了触媒添加元素的作用。结果表明：ＣＨＳ－３触媒为单相固浴体会金，有较好催溶性能，合成范围宽，所需合成压力低，能粗化金刚石晶粒，适用于合成粗颗粒高强度人造金刚石。The title catalyst metals for high-quality diamond synthesis have been investi-gated by means of x-ray diffraction and TEM,The effect of the synthesis process parametersand addifion elements in the catalyst on diamond synthesis are discussed in this paper,It isshown that as a homogeneous solid solution,CHS-3 catalyst offers some advantages such asability to improve the solubility of graphite,allowance to synthesize diamond crystals at awide temperature range and lower pressure,capability of coarsening the diamond grains andSuitability for synthesizing high-strength coarse-size diamonds.
