Mineral porous material because of its excellent performance in physical, chemical and structural widely used in environmental, chemical, pharmaceutical and other fields , has been much emphasis on developing and producing new mineral porous materials . In this paper, Cenosphere , fly ash, coal gangue and diatomaceous earth as aggregate materials , bentonite, glass powder and water glass as binder materials , charcoal , coal , edible starch and soluble starch as the raw material of the pore-forming agent , compression molding and conventional sintering method mineral porous material . Impact on the performance of products of the type of raw materials , formulations, process parameters , etc. , obtained the following conclusions: ( 1) Aggregate determines the basic performance of the products in the four experimental aggregate raw material , make the products have good Cenosphere the adsorption properties and high temperature stability , it is most suitable aggregate materials . ( 2 ) binder affect the forming and firing strength use floating beads as aggregate , In experiment three binder raw materials , bentonite under normal temperature conditions to make products easy to shape , and firing products the wear rate, is the most suitable binder material . (3 ) pore-forming agent to affect the pore structure and strength experiment four pore-forming agent of raw materials , toner best overall performance of the products from the pore-forming agent , is the ideal pore-forming agent ; increase the pore-forming dosage, the pore structure by the single-hole mesh communication hole . (4 ) firing temperature affect the pore structure of the products , strength and adsorption capacity of copper ions in the range of 1000 ° C -1250 ° C , the higher the temperature , the higher the porosity of products , the wear rate is lower , the removal of copper ions The rate is also lower . When the temperature of 1100 ° C , the porous material has good overall performance . ( 5 ) In Cenosphere , as aggregate , charcoal as a pore-forming agent , bentonite as a binder , molding, conventional fired prepared showing excellent performance, low-cost mineral porous material . The articles in the following properties : porosity of 48.42% , the wear rate of 6.58% , the load amount of 1.1mg / g . (6 ) Floating Bead mineral aggregate firing porous material products, silica-alumina phase for different crystal forms mullite ( 3Al 2 < / sub > O , 3 · 2SiO < sub> 2 ) and silicon sillimanite ( Al 2 < / sub > O 3 < / sub > · SiO , 2 < / sub > ) .
