The stable or unstable state of the montmorillonite-water dispersion is mainly effected by the properties of montmorillonite, water, and stabilizers as well as their interactions, while the type, the structure, the properties and the concentration of the stabilizer play dominate roles.

At the same time, a systematic mechanism of the hightemperature stabilization of the dispersion was presented.
