α‐SiC and β‐SiC crystals are prepared from vapor by sublimation of β‐SiC powder subjected to a conically converging shock‐wave generated by detonating an explosive charge. α‐SiC crystals are mainly 6H modifications and their features are plates, pyramids, needles, and filaments grown in the [0001] direction; 4H‐SiC filaments are also obtained. α‐SiC rods having a triangular cross section develop parallel to the [111] direction.
