High Temperature Crystallization of Zeolite NaA

这是对一种新技术的探索性研究，该技术用于生长大(约一厘米或更大)沸石晶体，沸石是一种在分离过程(离子交换、吸附等)中有许多应用的材料。和催化作用。目前可用的沸石晶体的尺寸范围是1到10微米(即，千分之一到千分之一厘米)。厘米级晶体的可获得性将为系统研究这种晶体的结构、研究表面热力学和输运现象以及制备由均匀单晶制成的分子“膜”提供机会。有可能对许多目前已知的分离技术产生重大影响。

This is an exploratory investigation of a novel technique for growing large (in the size range of about one centimeter or larger) crystals of zeolite, a material that has numerous applications in separation processes (ion-exchange, absorption, etc.) and catalysis. Currently available zeolite crystals are in the size range of 1 to 10 microns (i.e., one-ten-thousandth to one-thousandth of a centimeter). Availability of crystals in the centimeter range will provide opportunities for systematic studies of the structure of such crystals, studies of surface thermodynamics and transport phenomena, and preparation of molecular "membranes" made of uniform single crystals. A significant impact on many of the currently-known separation techniques is possible.
