| 中文摘要 | transparent and homogeneous aluminophosphate gels and glasses have been widely synthesized through an aqueous sol-gel route, extending significantly the glass-forming range compared to that accessible via the melt-cooling route. different phosphorus precursors, sodium polyphosphate (napo3) and orthophosphate species (nah2po4 and/or h3po4) were compared with regard to the macroscopic properties and the microscopic structure of the resultant gels and glasses as characterized by extensive high-resolution liquid- and solid-state nmr. sodium polyphosphate solution results in a substantially wider composition range of homogenous gel formation than orthophosphate solutions, and the two routes produce significant structural differences in the sol and xerogel states. nevertheless, the structures of the glasses obtained upon gel annealing above 400 degrees c are independent of the p-precursors used.
