China's silicate layered was rich, it was proved in China only on the content of bentonite was 23 million tons, more than 400 mine points in more than a dozen province.But the production was only about 200 wt.However, due to China's simple technology level, and no special equipment supported, product quality and other factors lead to instability low level of development of bentonite in our country's, and low efficiency.In the international market showed a low imports and high export.China's exports of Ca-bentonite price of 200-300 yuan /t, while the import price of organic bentonite 1500 yuan/t.Therefore all of our in-depth development of bentonite was placed in front of numerous scientific research workers.In recent years, China's development of the layered silicate had made considerable progress.China's scientific researchers focused on the development of organic intercalation, inorganic intercalation and three types of polymer intercalation, where the three intercalations pillared response to a certain degree of analysis and research.
