Silicon carbide dendrite (micrometer size) is produced by carbothermic reduction of rice husk ash in an arc plasma. Transmission electron microscopy reveals the occurrence of equispaced primary arms (60-70 nm in length) in the dendrite consisting of nanorod bundles. Each nanorod is seen to contain thin transverse lamellas, which appear like slip bands/twins in atomic layer thickness. A liquid phase Si-based growth mechanism is discussed to understand the dendrite growth.
