Abstract

A SiC nanopowder with an Al-based layer synthesized by means of laser pyrolysis was used to fabricate bulk SiC using spark plasma sintering (SPS) at 1600 – 1800 °C. The surface structure of the novel SiC nanopowder was analyzed by means of field-emission scanning/transmission electron microscopy (FE-SEM/TEM), while the surface chemistry was characterized using X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDS). The average particle size was around 45 nm with a very thin (
