Abstract: The present invention provides an artificial synthesis process and equipment for converting natural graphite powder particles into large flake graphite. This equipment consists of two ring-shaped, semi-circular or non-semi-circular grooves that can rotate relative to each other, along with other auxiliary devices; balls are placed within these grooves, and when the graphite powder particles enter them, they are subjected to the rotational pressure exerted by the groove walls and the balls, thereby being converted into large flake graphite.

Graphite can be converted into diamond at pressures of 50,000 to 60,000 atmospheres (((5-6)×103 MPa)) and temperatures ranging from 1,000 to 2,000 degrees Celsius, using metals such as iron, cobalt, and nickel as catalysts. The diamond particles synthesized initially were black, 0.5 mm in size, and weighed about 0.1 carat (diamonds used for jewelry generally need to be at least 0.1 carat in weight). Currently, the large-grain diamonds developed in our country are over 3 mm in size, while the United States, Japan, and other countries have already produced diamonds weighing more than 6.1 carats.

Moderator, moderator, can answers that are off-topic still earn points? ? ? ? :Lol, original poster, generally, a carbonaceous material is first selected, and then it goes through processes such as crushing, calcination, mixing, shaping, graphitization, and trimming to be produced. Find a book on carbon and flip through it for ten minutes. :victory:
