Studies on the Thermal Stability of Nano-SiC Powder with Excessive Free Carbon by Thermal Analysis-Mass Spectrometry Coupling Technique

摘要

TG-DSC-MS coupling technique is used to study the thermal stability of the nano -SiC powder with excessive free carbon. X-ray diffraction (XRD) is used to characterize the phase structure of the nano-SiC powder. TEM is used to observe the particle size and the shape of the nano-SiC powder with excessive free carbon around the thermal treatment. The TEM results are showing no difference with that obta ined by thermal analysis mass spectrometric technique
