Pillared trioctahedral micas and/or vermiculites are prepared. The process includes a conditioning operation for the partial reduction of the layer charge through an accelerated weathering process, and also includes a pillaring operation.
1. Pillared vermiculites precalcined or not and/or trioctahedral micas obtained according to the process comprising: conditioning the micas and/or vermiculites through accelerated weathering so as to partially reduce the layer charge of the micas and/or vermiculites, wherein conditioning the micas and/or vermiculites comprises successive steps as follows: a) treating the micas and/or vermiculites with a solution of an acid; b) calcining the product recovered from step a) at about 600° C. for approximately 4 hours under static air; and c) treating ...
