Gas　atomization　was　usually　regarded　as　a　good　method　for　producing　the　spherical　or　approximate　spherical　powders.　We　found　a　lot　of　non-spherical　powders　in　production　processes,　especially　in　larger　particle　size　distribution　area.　The　causes　of　producing　non-spherical　powders　are　explained　and　some　analyses　are　done　in　order　to　find　a　better　condition　of　producing　spherical　powders　in　this　paper.　The　following　morphologies　were　obtained　by　atomized　Fe50　Co50　and　pure　iron　and　investigated　by　scanning　electron　microscopy　(SEM).
