Abstract :
A simulation method was used to investigate the effects of experiment parameters on particle formation of 63Sn-37Pb based on POEM. The results show that stable particles could be obtained only with adequate clearance. Particles with various sizes are obtained by rationally controlling the diameter of orifice, rod velocity and applied pressure. 63Sn-37Pb mono-sized sphere micro particles with different sizes were prepared by POEM, the experimental results are consistent with that of simulation.
