A series of C/SiC composites was successfully synthesized via the carbothermal reduction of carbonaceous silicon xerogel, which was prepared from the sol gel method by using tetraethoxysilane TEOS and saccharose as the raw materials The obtained samples were characterized by X ray powder diffraction XRD and N 2 physical adsorption The specific surface areas of the as prepared C/SiC composites...
In this study, we combined the traditional vacuum furnace with a sur-high accuracy vacuum gauge for measuring the change of gas pressure in the furnace as a function of temperature. The modified vacuum furnace was used for preparing silicon carbide (SiC), and the recorded data named thermobarogram were applied to detect the reaction temperature for synthesis of SiC, which, in particular, changes as...
