Physicochemical Properties of Erdos Analcime in NeiMongol Area

The mineral of Erdos Analcime from NeiMongol Area was studied by chemical analysis,XRD,FT-IR,DSC,N_2 static adsorption at 77 K and the cation exchanges of K~+,NH~+_4 and Cu~(2+).The results showed that Erdos Analcime belongs to the ferric-magnesium typed analcime,in which hydrocerussite,orthoclase,jadeite and ferric oxide are company minerals,and Fe~(3+) takes part in the framework construction of analcime because the parameter of crystalline cell of the analcime in the mineral is larger than that of the ideal crystalline cell.Meanwhile,the structural hydroxyles of analcime and hydrocerussite in the mineral are released by structural water at 500 ℃~700 ℃,bond water is released at 120 ℃~360 ℃.Because the specific area,the pore volume and the cation exchange capacities of K~+,NH~+_4 and Cu~(2+) are smaller,the modified method of Erdos Analcime must be studied further in order to be applied.
