e由gzhuang guisuanyan llegou层状硅酸盐结构(layer silie。te strueture) 由硅氧四面体〔510‘〕在二维空间通过共用氧连接成层状(或片状)络阴离子的硅酸盐结构亚类。层状络阴离子通过共用氧与铝(镁)氧八面体相连，按连接方式的不同分为单层和双层结构，前者如高岭石A12(51:O。)(OH)‘，后者如叶蜡石AI:(51;01。)(OH):。(见图)层与层之间主要由范德华力和氢键连接，在水中易分散成微粒而形成胶团。当结构中514+被A13十或A13+被Mg2+取代时，能形成蒙脱石、云母等矿物。层状结构可以看作链状结构交连而成。按链的周节数，已发现的有2、3、4、5、6节链构成的层状结构以及分支、环枝单层状结构和分枝的双层结构。 汽产中即户怨 万~、认才V水八八八人^‘40+20H 、认了甘卜从J了丫丫冶尹节产4AL 夕F代洲沁、J丫气J、从研Qb口db 40+20H 飞砰一书厂屯太五人451 势心只户。丈夜田U叮丫6O ab 高岭石(a)和叶蜡石(b)的层状结构 (李晓明)
