Method of processing polycrystalline diamond material
A method of processing a polycrystalline diamond (PCD) material having a non-diamond phase containing a catalyst/solvent material, the method comprising leaching an amount of the catalyst/solvent from the PCD material by exposing at least a portion of the PCD material to a leaching mixture, the leach mixture comprises hydrofluoric acid at a molar concentration of between 12 M and about 28 M, nitric acid at a molar concentration of between about 3 M and about 10 M; and water.
一种加工具有含有催化剂/溶剂材料的非金刚石相的多晶金刚石(PCD)材料的方法，所述方法包括通过将所述PCD材料的至少一部分暴露于浸出混合物从所述PCD材料中浸出一定量的所述催化剂/溶剂，所述浸出混合物包含摩尔浓度在12M至约28M之间的氢氟酸、摩尔浓度在约3M至约10M之间的硝酸；以及水。
