Significant alterations in the surface morphology of α‐silicon carbide powders have been observed after exposure to a low‐temperature Ar plasma. Surface alterations were observed in 3 min at 1900°C and 30 min at 1600°C. Powders heated with plasma exposure were characterized by contact development and particle rounding whereas without the plasma substantial faceting was observed at higher temperatures.
