SMECTITE(BEIDELLITE) FROM PAGODITE AND SYNTHESIS OF SMECTITE(BEIDELLITE)

摘要

The present invention is a natural rock, such as, dickite on smectite and its synthesis method using pyrophyllite and the pyrophyllite as a starting material significantly reduced the reaction temperature, pressure and time by preparing the smectite, and for the purpose of setting to reduce the production cost. ; smectite using pyrophyllite according to the invention as set forth is, dickite, kaolinite, and the one selected as the starting material of the group comprising light Nak, the starting material is mixed with sodium carbonate is 1 car, and then the mixture is mixed with amorphous silicon dioxide in water, sequence the synthesis is made. Smectite synthesis method according to the invention using pyrophyllite, dickite, kaolinite, and the pre-treatment step of heat treatment after the mixing of the starting material and any one selected from the group comprising sodium carbonate Nak light; Mixing the raw material with a silicon dioxide prepared by the pre-processing step in water to prepare an aqueous solution and adjusting the alkalinity of the aqueous solution; Then, while stirring the mixture in the mixed solution is prepared by reacting step comprises a step of producing a single hydrothermal synthesis reaction on the smectite.
