Synthesis of SiC Whisker from the SiO_2-C-Na_3AlF_6 System AITranslate
Abstract AITranslate
SiC whiskers were synthesized with SiO2 powders, graphite and NaaAlF6 as the raw materials. The products were analyzed by XRD and SEM. The results show that the products synthesized with Si/AI molar ratio of 4 ： 1 and at 1 500 ℃ is of the best quality. The whisker synthesis mechanism is discussed. It is presumed that the whisker growth follows VS mechanism and Na3AlF6 doesn＇t react during the actual synthesis process. About 0. 005 supersaturation degree of the gas reactants is calculated,as is good for the growth of whiskers.
