蛭石是一種與蒙脫石相似的粘土礦物,為層狀結構的硅酸鹽。一般由黑云母經(jīng)熱液蝕變或風化形成。它有時以粗大的黑云母樣子出現(xiàn)(這是蛭石的黑云母假象),有時則細微得成為土壤狀。把蛭石加熱到300℃時,它能膨脹20倍并發(fā)生彎曲。這時的蛭石有點像水蛭(俗稱螞蟥),因此它有了這么一個名字。蛭石一般為褐、黃、暗綠色,有油一樣的光澤,加熱后變成灰色。蛭石可用作建筑材料、吸附劑、防火絕緣材料、機械潤滑劑土壤改良劑等等,用途廣泛。

蛭石的主要化學式為(Mg,Ca)0.7(Mg,F(xiàn)e,Al)6.0[(Al,Si)8.0](OH4.8H2O)。常見化學式為 (Mg2.36Fe0.48Al0.16)(Si2.72Al1.28O10(OH)2)(Mg0.32(H2O)4.32)

蛭石可按階段性可以劃分為蛭石片和膨脹蛭石,按顏色分類可分為金黃色蛭石、銀白色蛭石、乳白色蛭石。

蛭石片經(jīng)過高溫焙燒其體積可迅速膨脹6-20倍,膨脹后的比重為60-180kg/m3,具有很強的保溫隔熱性能
