一、天然沸石概述 沸石系含水的钾、钠、钙、镁等的格架状铝硅酸盐矿物。其一般化学式为:A_m XpO_2p·nH_2O。式中A为钙、钠、钾、钡、锶;X为硅、铝。沸石灼烧时,晶体内的水分被赶出,产生类似起泡沸腾的现象,因而称为沸石或泡沸石。沸石的晶体结构特点:硅(铝)氧四面体是组成沸石结构的基本单元;硅(铝)氧四面体通过公用顶点彼此连接构成各种形式的格架;在格架中有许多孔道和孔穴,通常水分子充填
First, the natural zeolite Overview Zeolite is water-containing potassium, sodium, calcium, magnesium and other grid-like aluminosilicate minerals. The general formula is: A_m XpO_2p · nH_2O. Where A is calcium, sodium, potassium, barium, strontium; X is silicon, aluminum. When the zeolite burns, the moisture inside the crystal is expelled, resulting in a bubbling-like phenomenon, hence the name zeolite or zeolite. The zeolite crystal structure features: silicon (aluminum) oxygen tetrahedron is composed of zeolite structure of the basic unit; silicon (aluminum) oxygen tetrahedron connected to each other through common vertices to form various forms of grid; in the grid there are many channels and holes , Usually filled with water molecules
