For instance, acidic pH was related to the formation ...

Introduction to Halloysite Filler. Halloysite filler is a natural nano clay with identical chemistry to the more common kaolinite clay. There has been a huge amount of hype around this product but actual commercial applications have been very slow to develop. The performance is not sufficient to justify the price, or in many instances, the ...

The results have shown that montmorillonite has the largest adsorption capacity followed by ZrO-montmorillonite, TBA-montmorillonite, kaolinite, ZrO-kaolinite and TBA-kaolinite. Introduction of ZrO- and TBA- groups into the clays reduced their adsorption capacity by blocking the available adsorption sites.
