In 1756, a mineralogist named A.F.

In 1756, a mineralogist named A.F. Cronstedt discovered the first of a group of minerals that,
when heated, appeared to boil. Cronstedt soon realized that the boiling effect was due to very fast water
loss. The observation that the mineral had been able to hold so much water within it suggested that it was
very porous, and as Cronstedt and other scientists further explored the molecular structures of such
minerals they were determined to have very open molecular frameworks. Cronstedt named this group of
micro-porous minerals zeolites (from the Greek “zein” and “lithos”, meaning “stones that boil”) [1].
More specifically, a zeolite is a hydrated alumina-silicate mineral that has a very micro-porous structure.
The corners of the structures are composed of [AlO 4 ]- and [SiO 4 ]- tetrahedra. In order for a mineral to be
considered microporous, the channels or pore openings must be less than 20 Å. Most zeolites have pore
openings much smaller than this. In general, zeolites (also called “molecular sieves”) are defined to be
three dimensional frameworks of tetrahedrally coordinated atoms (T-atoms) with cavities or channels for
which the smallest opening is larger than six T-atoms [1].

在 1756 年，名为释疑 Cronstedt 矿物学家发现第一组矿物，当加热时，出现沸腾。Cronstedt 很快意识到沸腾的效果是非常快的水损失。矿物已经能够容纳这么多的水，在它之内的观察指出，很多孔，以及 Cronstedt 和其他科学家进一步探讨这种分子的结构矿物他们有决心有非常开放的分子框架。Cronstedt 给这群名字微多孔矿物沸石 （来自希腊"玉米醇溶蛋白"和"lithos"，煮的含义"石头"） [1]。更具体地说，沸石是一种水合的氧化铝硅酸盐矿物，具有一个非常微多孔结构。角落的结构是由组成的 [AlO 4]-和 [SiO 4]-四面体。一种矿物，是为了考虑微孔，渠道或孔隙通道必须小于 20 Å。大多数沸石有孔开口比这小得多。一般情况下，沸石 （也称为"分子筛"） 被定义为在三个三维框架的腔或渠道的四面体配位原子 （T-原子）其中最小的开放大于六个 T-原子 [1]。

1756，一个名叫A.F. Cronstedt发现一批矿第一，加热时，出现沸腾。克朗斯塔特很快认识到沸腾效应是由于很快水损失。的观察，矿物已经能够保持这么多的水在它的建议，它是多孔的，和克朗斯塔特和其他科学家进一步探索这样的分子结构矿物，他们被确定有非常开放的分子框架。克朗斯塔特命名这一组微多孔矿物质沸石（来自希腊语“玉米”和“石”，意思是“石头滚”）[ 1 ]。更具体地说，沸石是一种水合的氧化铝硅酸盐矿物，具有非常微细的多孔结构。结构的角是由[ 4 ]和[ ALO SiO 4 ] -四面体。为了一个矿物考虑微孔，渠道或开孔必须小于20Å。大多数沸石有孔隙开口远小于这个。在一般情况下，沸石（也被称为“分子筛”）被定义为四面体配位原子的三维框架（T-原子）与空腔或通道它的最小开度大于六T-原子[ 1 ]。
