Layered sodium silicates are one kind of inorganic crystal with the property of intercalation. They have many superior properties, such as ion exchange and sorption. So they have been used as ion-exchanger and adsorbent. In addition, layered sodium silicates can be used as the base for synthesis of layered self-assembly intercalation materials and used as starting compound for the synthesis of the novel microporous materials. Thus, layered sodium silicates are important layered silicates. Therefore,...
