Study on Physicochemical Properties and Application Prospect of Several Typical Bentonite

Abstract:

Four kinds of bentonite samples were studied in this paper. Mainly discussing the particle size distribution, mineral composition and physicochemical properties of bentonite, the aim was to provide a useful reference for the efficient development and utilization of bentonite resources. The results indicated that NM-bent., HB-bent. and EZ-bent. were Ca (Mg)-bentonite while XZJ-bent. was Na-bentonite. The physicochemical properties of bentonite mainly depended on interlayer cations. Many properties indexes of Na-bentonite were better than that of Ca (Mg)-bentonite. Some properties indexes showed a poor reproducibility when tested by standard methods. The natural Na-bentonite has excellent properties and extensive application prospects while Ca (Mg)-bentonite needed for further processing to meet the demand of the application field.
