Nanorods of silicon carbide from silicon carbide …
Nanorods of silicon carbide were found to be produced directly from silicon carbide powder when subjected to high temperature heat treatment. The powder with 20–50 μm grain size was kept in a graphite crucible (enclosed in a chaer/furnace) and heated from its bottom at 2700 °C for 15 min by employing a typical configuration of arc plasma (Ar). The heating was then followed
