抄録

Smectite was formed from some clays, such as pyrophyllite, kaolinite, sericite and talc by reaction with NaOH solution at 100℃ under atmospheric pressure.Smectite was formed well under the condition that the concentration of NaOH was near 2M〜3M.Furthermore, when the reaction time involved is within 50 days, the amount of starting material should be less than 0.5g in 100ml solution to form smectite.
