英文摘要Using tire semi-coke as carbon source and silicon sand as silicon source, silicon carbide(SiC) was prepared by carbothermal reduction method at 1520. XRD, SEM and FTIR spectrometer were used to characterize the SiC prepared under different raw material particle size conditions. The influence law of raw material particle size on the phase, morphology, particle size and reaction degree of the synthesized SiC was investigated. The results show that the size of the raw material has a very important influence on the degree of synthesis reaction and the phase composition, morphology and size of the product.Within a certain particle size range, with the decrease of silicon sand particle size, SiC crystal type becomes complete and SiC whisker decreases gradually, while the SiC particle size distribution does not change significantly.With the increase of semi-coke size of tire, the product phase gradually becomes single, and the proportion of SiC particle size and whisker decreases gradually. In addition, by measuring the C/Si ratio in the product and confirming the presence of the intermediate product SiO, it is inferred that the formation mechanism of SiC particles is gas-solid (VS) reaction, while the formation mechanism of SiC whiskers is gas-gas(VV) reaction. 漏 2021, Editorial Board of CIESC Journal.
