Development of hybrid microspheres for assessment of multiphase processes

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.
