Abstract : The effect of adsorption temperature, octadearyldimethyl-ammonium dosage, washing temperature， oscillation time, oscillation intensity, using temperature and pH value of exchange fluid on the stability of the composite powders was studied. The results show that the effect of adsorption temperature, octadearyldimethylammonium dosage, pH value of exchange fluid and washing temperature on the stability of the composite powders is significant. The stability of the composite powders is better with higher adsorption temperature, smaller octadearyldimethyl -ammonium dosage, larger pH and lower washing temperature. The dispersion time, oscillation intensity and using temperature have less influence.

Keywords: montmorillonite; octadecyltrimethylammonium chloride; composite powder; stability
