摘要
在Na2O-CaO-B203-Al2O3-H2O-R体系中（R代表有机胺）,应用水热晶化法合成了两种具有新的骨架结构的微孔硼铝酸盐分子筛,结构中硼与氧配位的基本结构单元为平面三角形（三配位）和四面体（四配位）。吸附性能的测定表明这类微孔材料的孔径大小在0.5～0.6nm之间。
Novel microporous boro-aluminates were synthesized through hydrother system of Na2O-CaO-B2O3-Al2O3-H2O-R.The results of XRD, IR and XPS show that the boro-aluminates possess novel frame-work structure. Basic building blocks are BO3 and BQ4. These boro-aluminates possess characteristics of ab-sorption form like that of molecular sieves after the absorption of free water molecules and other species.
