In system “Pd(NO3)2 - Al2O3 - La2O3 - HAc - H2O" calculation of ion equilibrium with use of thermodynamic constants are determined by boundary conditions of formation of hydroxides of metals Possibility of decrease in dynamic viscosity of the “Pd(NO3)2 - Al2O3 - La2O3 - HAc - H2O”, suspension having pH = 3 at addition of 1% of an aqueous solution is experimentally shown cation-active surfactant at 1.74 time: with 850.62 to 488.95 mPa•s. The morphology of particles of suspension before and after the addition in it surfactant cation-active Praestol 655 FC is investigated.
