Considered that the metal (alloy) plays the role of carbon in a solvent

Solvent doctrine that the metal (alloy) plays the role of carbon in a solvent; catalytic doctrine is considered to be a catalyst; solid phase transition theory emphasizes the disintegration of the graphite crystal without bond breaking, after a simple  Diamond blade  on the formation of diamond crystals. But the doctrine of three typical models are often made ​​with some of the main experimental phenomena and laws are  abrasive wheels . Thus, over the past decade, there has been a solvent - catalyst, the catalyst - solvent, melting (melting) agent - catalyst (referred to as the melting media) and other theories to further explore the use of metal (alloy) role. In general, synthetic diamond formation mechanism currently still being explored is a complex problem.
