Abstract:
The purity of montmorillonite from five manufacturers was investigated for qualitative and quantitative analysis. The characterization of montmorillonite from five manufactures was investigated by SEM,FTIR and PXRD,and the concentration of cristobalite and α-SiO2 in montmorillonite were determined by PXRD. The results showed that montmorillonite from five manufactures,all conform to the rules,but the quality of the samples with different manufacturers varies. The montmorillonite from D manufacturer has superior quality,which should be the first choice for the preparation production enterprises.
