蒸汽相中含硼多孔玻璃自转变合成沸石 Ⅰ.固相表面反应

Studies on Zeolite Synthesis by Self-transformation of B-con taining Porous Glass in a Vapor PhaseⅠ. Solid-state Surface Reaction

以XRD、化学成分分析、SEM为主要手段 ,观察含硼多孔玻璃粉或玻璃板在有机胺与水的混合蒸汽相中自转变合成MFI型沸石与沸石膜 ,以及TON型沸石的结晶行为 .

The crystallization of MFI-type zeolite and its membrane, an d TON-type zeolite self-transformed from B-containing porous glass granules a nd porous glass plates in a vapor phase was studied by XRD, chemical composition analysis and SEM. The results provide strong evidence for that the crystalliza tion of self-transformation is a solid-state surface reaction process.
