A novel method is reported to produce fine Ca metal powder for the first time This method used centrifugal atomizer with rotating quench bath in inert gas The atomization occurred at disk edge by ligament disintegration mode Smaller atomized Ca powders tend to be more spherical than larger powders Fine atomized Ca powders are more stable than its high purity counterpart
