Synthesis of silicon carbide hydroxyhapetite composite via ball milling

May 01, 2013 May 01, 2013 A carbon–silicon carbide (C p –SiC) composite powder was prepared with nano-carbon (C p) and silicon (Si) powders as starting materials via a mechanochemical treatment in Ar atmosphere in a stirred ball mill. The composite powder was characterized by X-ray diffraction (XRD), thermogravimetry/differential scanning calorimetry (TG/DSC), scanning electron microscopy (SEM)
