IT was shown by Seal 1 that little change was produced by heating natural diamond powders to 1,200° C. in a vacuum (10 −4 mm. mercury) for periods of 15–30 min. Heating the powders to 2,000° C.

Washington, Dec 11 (PTI) Scientists have for the first time turned diamond into graphite using ultra-short flashes of an X-ray laser. Trending Now It is a decisive step forward in understanding the ...

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...

Discuss the implication of growing diamonds: In the NOVA scienceNOW video segment, Neil visits a "diamond farm"—a secret location where the diamonds are "chemically, physically, and optically ...
