Development of hybrid microspheres for assessment of multiphase processes.

ABSTRACT

This work presents a new technique for the synthesis of particles satisfying the conditions of several multiphase suspensions. It consists of manufacturing PMMA_La2O3 hybrid microspheres through suspension polymerization first and then submitting the beads to neutron activation. It was found that the fractional mass of the filler La2O3 in the beads can be greater that 60% using this technique. The results and other properties of the particles clearly indicate that the technique is effective to produce particles for several RPT applications.
