The catalytic material has always been the key to the synthesis of synthetic dia-monds,and it is also one of the main sources of cost for synthetic diamonds.The article provides a detailed review of the development process of diamond synthesis catalyst mate-rial technology in China over the past 60 years,from research on catalyst material tech-nology under planned economy conditions to the development and maturity of flake cata-lyst technology,to the repeated introduction,absorption,and continuous research and in-novation of powder catalyst material technology under socialist market economy condi-tions.We pay tribute to and thank the predecessors who have made contributions to the development of diamond.More importantly,the research of Chinese diamond industry practitioners in diamond synthesis catalyst material technology has not been interrupted,and the pace of progress has not stopped,and it will continue to develop.
