The problems of diamond synthesis and the problems of bonding diamond are intimately related. No one has ever succeeded in achieving a decent polycrystalline diamond compact, bonded outside of the stability field of diamond. Further, all bonding not only must be in the stability field of diamond but must be in the presence of a molten carbon solvent such as invar, stainless steel or cobalt. Thus, the apparatus required to synthesize diamond is essentially the same as the apparatus required to bond diamond.
