Abstract: A method for producing carbon powder having a defined carbon particle size distribution comprises the steps of: —a) selecting a carbon precursor powder of a defined precursor particle size distribution, the carbon precursor powder consisting of or comprising particles of one or more meltable carbon precursors; b) treating the carbon precursor powder to round at least some of the particles of the carbon precursor and thereby produce a rounded carbon precursor; and c) carbonizing the rounded carbon precursor; wherein the defined precursor particle size distribution is such that on carbonization the powder of defined carbon particle size distribution is produced.
