Seed crystal distribution method for synthesizing colorless diamond by powder catalyst constant-temperature method

The invention belongs to the technical field of superhard material manufacturing processes, and particularly relates to a seed crystal distribution method for synthesizing colorless diamond through a powder catalyst constant-temperature method. The seed crystal distribution method for synthesizing the colorless diamond by the powder catalyst constant-temperature method comprises three steps of prefabricating a graphite catalyst sheet, assembling a graphite core column and synthesizing the colorless diamond by the constant-temperature method, and comprises the following steps: firstly, premixing the graphite catalyst and a nitrogen removal agent powder, and then pre-pressing the graphite catalyst sheet; and finally, performing seed distribution design on the graphite catalyst sheets according to parameters such as granularity and growth space required by a product, and alternately assembling the graphite catalyst sheets subjected to seed distribution, so that the synthetic growth of high-quality seed crystals
