Summary of the EDX-analysis for SiC:

Spot 1Spot 2
Element Wt-% Atom.-% Wt-% Atom.-%
C 30.7 51.67 69.97 84.91
Al 0.93 0.7 0.44 0.24
Si 65.8147.37 28.47 14.77

The EDX-measurements clearly show that the powder mainly consist of SiC. Since the spot-to-spot analysis varies quite a lot it is indicated that the powder consists of unreacted carbon besides the pure Silicon carbide.
