Study on Na-activation Conversion Technology of Bentonite

Zhang Xiuying (College of Material Science & Engineering,Shandong University of Science & Technology,Zibo 255049)  
The Ca-bentonite from Shandong provice was used to produce Na-bentonite by suspensoid.The result shows that the selection of conversion agent kind is the key step in processing.The best reaction conditions are as following:the conversion agent is NaF;its dosage is 4%;conversion time is 90min; conversion temperature is 80℃.X-ray diffraction shows that d(001) is 1.2838nm;the properties of converted bentonite have been improved.
