日本科学技术厅无机材料研究所以非金属无机化合物为催化剂,开发出新的金刚石高压合成法。常规的金刚石合成法是使用Fe、Ni、Co以及Nb-Cu合金等金属催化剂与石墨在高压下进行反应而获得金刚石,已有30年以上的历史,并实现了工业化。此次该研究所在世界上首先开发出以碱土金属的碳酸盐(碳酸锂、碳酸钙、碳酸锶等)、硫酸盐(硫酸镁等)、氢氧化物(氢氧化镁等)作催化剂 Japan Institute of Science and Technology inorganic materials Institute of non-metallic inorganic compounds as a catalyst to develop a new high-pressure diamond synthesis. The conventional diamond synthesis method is to obtain diamond by using metal catalysts such as Fe, Ni, Co and Nb-Cu alloy and graphite to react under high pressure for more than 30 years, and industrialization has been achieved. The Institute in the world first developed the use of alkaline earth metal carbonate (lithium carbonate, calcium carbonate, strontium carbonate, etc.), sulfate (magnesium sulfate, etc.), hydroxide (magnesium hydroxide, etc.) as a catalyst
