摘要
Currently, the common way for structural investigation is to confirm the amorphous state of the quenched slag by XRD prior to Raman analysis. However, if the slag precipitates a few nanocrystals during quenching, XRD may not recognize them, but the slag structure has been changed. Therefore, this paper proposes to combine TEM with XRD and Raman for analyzing the slag structure and to verify it with blast furnace slag obtained by different quenching methods. The results show that the XRD curves of the slags obtained by quenching in water or on a stainless steel plate show amorphous states, but the deconvolution results of Raman spectra are significantly different. The TEM analysis finds a few crystals in the slag obtained by the latter, which is responsible for the structural differences. Therefore, it is necessary to confirm the amorphous state of the slag by both XRD and TEM before studying the structure.
