What conditions are needed to transform graphene into graphite?
Are there any pressure-temperature specific conditions like diamond-graphite transformation?
Depends. Do you want to make actual "good" graphite or just graphite?
If you just shoot a laser at any carbon it will always graphitize but of course that won't give you a graphite crystal. Otherwise: if you perform any multilayer graphene synthesis too excessively you will end up with graphite of some sort, as well. After al, some people do not like the term "multilayer graphene" anyway and just see it as a thin graphite slab.
What particular goal are you trying to achieve?
Hello Jurgen,
Thank you very much for your answer. I do use graphene nano-pallets as an additition to ceramic powder for SPS sintering. I wonder what form of carbon could I expect: polycrystalline graphene or graphite or maybe some other form of carbon.
Kind regards
Tomasz
OK, in that case you will definitely get some sort of graphitic carbon. You start with sp2 carbon which is the most stable configuration so there is no reason why that would change in the process. If you put a lot of graphene layers atop of each other that is graphite - not in a good crystalline quality, but graphite nonetheless.
