A free impinging-jets microreactor was used for synthesizing rhabdophane-structured LaPO4 sols. The rheological behavior was investigated for the sols obtained both by reagents mixing in a microreactor, and by pouring the initial solutions together and mixing them on a magnetic stirrer. Lanthanum phosphate sols obtained by two ways are structured systems characterized by deformation behavior accompanied by shear liquefaction. Some discovered anomalies were found to be associated with flow nonequilibrium at low shear rates, which indirectly indicates stronger binding of particles in the structure of samples obtained by the microreactor synthesis.
