In this paper, we found that the change of sodium montmorillonite's (MT) concentration in the magnesium‐aluminum‐ferrum hydrotalcite‐like compounds (Mg‐Al‐Fe‐HTlc)/MT suspensions would greatly influence the thixotropic type of the suspensions. Specifically, the increase in the MT's concentration increases the viscosities ( η ) of the HTlc/MT suspensions with the same R value (the mass ratio of HTlc to MT was signed as R , e.g ., R = m HTlc / m MT ), meaning that the structure strength of the HTlc/MT suspensions increases. With the variation of MT's concentration, the thixotropic type of the HTlc/MT suspensions changed accordingly, and the mechanism has been discussed in this paper.
