KCl掺杂高纯度方钠石的合成

在硅铝酸盐胶体中掺杂KCl,采用水热法合成了高纯度的方钠石。考察了KCl掺杂量对合成方钠石的影响,研究表明:在不同含水量的硅铝酸盐胶体中掺杂KCl可以合成高纯度的方钠石,合成的方钠石均为球形颗粒,胶体中含水量越高,球形颗粒的粒径越大。为工业合成方钠石提供了一种新方法。

Synthesis of KCl-doped high purity sodalite

Sodalite single crystal was synthesized by hydrothermal method in the KCl-doped silicon alμminate colloid. The effects of the concentration of KCl on sodalite crystallization were investigated. It indicates that high purity sodalite can be synthesized in the KCl-doped silicon alμminate colloid with different water content. The all synthesized sodalite are spheroidal particle,the higher of water content in the KCl-doped silicon alμminate colloid,the larger of particle size of spherical particles. It provides a new method for industrial synthesis of sodalite.
