As shown in Fig. 3, the main crystalline compounds were calcite (CaCO3), halite (NaCl) and sylvite (KCl). In addition, the presence of crystal structures, such as calcium chlorite hydroxide (CaClOH), silicon chloride (SiCl4), calcium chloride hydrate (Ca(ClO)2•4H2O), iron sulfide (FeS) and portlandite (Ca(OH)2) were also verified. According to the diffraction pattern obtained by XRD, the main components of this sample include calcium chloride hydroxide, halite, silver aluminum sulfide, silicon chloride, stannite and sylvite, which confirms the results of XRF.¡±
ÕâÊÇÉó¸åÈ˵ÄÒâ¼û£º¡°Authors used XRD analysis for identification of the crystalline compounds of fly ash. Unfortunately, the analysis is only qualitative. The semi quantitative analysis could give better information about material composition. Moreover, it is well known that materials treated in high temperatures usually contain high amounts of amorphous phase. I would recommend to perform XRD analysis with some standard and to determine semi quantitative composition and content of amorphous phase, if possible.¡± Ëû˵£ºÎÒÕâ¸öXRD·ÖÎöÖ»ÊÇ ¶¨ÐÔ·ÖÎö£¬°ë¶¨Á¿·ÖÎö¿ÉÒÔ¸üºÃµÄÌåÏÖ²ÄÁϵÄ×é³É¡£ ²¢ÇÒ²ÄÁÏÔÚ¸ßÎÂÏ»áÓзǾ§Ìå²úÉú£¬ËùÒÔÉó¸åÈËÈÏΪ£¬Ó¦¸ÃÓÃijÖÖ±ê×¼À´½øÐÐXRDµÄ°ë¶¨Á¿·ÖÎö·É»ÒÖзǾ§ÌåµÄ×é³ÉºÍº¬Á¿¡£
