| Abstract: | The sorption isotherms of water and tetrachloromethane vapors are studied, and the porous structures of aluminum tin phosphate gels coprecipitated at various Al/Sn molar ratios are analyzed. The resultant samples contain both micro- and mesopores. The structure of aluminum tin phosphate is suggested to contain slitlike pores that do not change during drying because of the presence of polyaquahydroxoaluminum cations introduced via an exchange with interlayer cations of tin(IV) hydrophosphate. |
