Size distribution has been studied for nanoparticles of yttrium aluminum garnet prepared by the Pechini method and the one modified of precursors calcination in melted potassium chloride with following preparation of colloid solutions. The final calcinations of precursors in melted potassium chloride decrease both the size of nanoparticles and their agglomeration. The various techniques such as sedimentation , potential determination were used−ζdynamic light scattering, SEM and for investigation of yttrium aluminum garnet nanoparticles in colloid solutions. It was determined the size of agglomerates can be decreased m to 120 – 240 nm.µby the ultrasonic treatment from 10 – 15 The effect of different surfactants (sodium dodecylsulfate, glutamic acid, polyethylene glycol , etc.) on the stability of garnet nanoparticles in colloid solutions was demonstrated with estimation of optimal surfactant concentration about 1-2 wt/%. It was established the colloid solution of yttrium aluminum garnet without surfactant is stable at pH > 7.5. Addition of surfactants to colloid solution demonstrates the colloid solution’s stability at lower pH values.
