Twostep ballmilling synthesis of a Si/SiOx/C composite ...
C3 sample obtained by twostep ballmilling method. In order to further clarify the presence of SiC phase, the XRD patterns of pure SiC and Si/SiO x/C3 composite fabricated by onestep ball milling were conducted as shown in Fig. S2.† We can observed the typical peak at corresponding to the pure SiC that clearly show the presence of SiC.
