摘要
对钟祥累托石粘土的改色和有机覆盖进行了研究。结果表明，可利用原矿中的可溶性Ｆｅ３＋或外加Ｆｅ３＋与碱反应进行改色，可使累托石由深灰－灰黑色变为褐黄色；用季铵盐覆盖可制备出吸油膨胀达十倍以上的有机累托石。
Tests on color modification and coating with organism were carried out for the rectorite ore.The results shown that the clay can be changed into brown from dark grey by using NaOH to react with the soluble Fe 3+ within the ore or applied.The organo-rectorite with expansion coefficient of over 10 times can be obtained by coating with quaternary ammonium cations.
