Abstract
A method of forming polycrystalline diamond comprised placing a plurality of graphene nano-platelets into a capsule; and subjecting the platelets to a pressure of around 10 GPa to around 20 GPa and a temperature of around 1600 degrees Celsius to around 3000 degrees Celcius to convert the graphene platelets to nano-polycrystalline diamond. There is also disclosed a polycrystalline super hard construction comprising a polycrystalline diamond region comprising polycrystalline diamond material formed according to said method.
