It is interesting that with the same raw material, A, the crystalline forms of the products treated by calcination are different at different temperatures, i.e., the calcined products at a temperature of 400OC or 700OC, 500 and 600 are B, C and D, respectively. Fig. 1 shows the XRD peak of different calcined products, which exactly coincide with their standard spectrums. This result indicates that the calcined products of A at different temperatures are really different, which may be related to the different temperatures when the crystals form. As we know, it has not been reported that the crystalline forms of C from the same raw material can be controlled by calcination at different temperature. Our finding provides a good way for the stereospecific synthesis of C with different crystalline forms. ½ö²Î¿¼£¬×¨ÒµÃû×Ö²»Ò»¶¨¶Ô£¬²¢ÇÒÕâ¶Î»°ÊÇÔÚÊÇÌ«†ªàÂÁË£¬·¹ýÀ´µ÷¹ýÈ¥¾ÍÊÇÒ»¸öÒâ˼ |
