| Abstract: | A new method is presented for direct synthesis of hexacoordinate silicon complexes from serpentine ore residue after extracting magnesium by atmospheric distillation. The structure of products was analyzed by IR and XRD. The results show that the products synthesized are hexacoordinate silicon complex. The optimum synthetic conditions determined by experiments are as that the flow rate of N2 is 50 ml/min, reaction time is 2. 5 h and the relative distillation amount of ethylene glycol is 75%. Under such conditions, the yields of barium salt and calcium salt are 86. 5% and 54. 6% respectively. |
