在甲胺和水的蒸汽相中，多孔玻璃粉自转晶为高结晶度纯相含硼TON类型的CF- 2沸石。~(11)B MAS NMR证明硼原子基本上进入了沸石骨架。扫描电镜照片显示， 合成的CF-2沸石中既有单个晶体，也有由许多单个晶体构成的扇形聚集体。单个晶 体呈长条形。

Boron-containing CF-2 zeolite with high crystallinity and purity, which is first reported, was synthesized by self-transformation of porous glass granules in the vapor phase of methylamine and water. ~ (11)B MAS NMR spectra prove that the atoms of B in the raw glass have been essentially completely incorporated into the zeolite framework. The as-synthesized crystals of CF-2 zeolite are rectangular rod-shaped. Some of the crystals are individuals and the others are aggregates.
