  . The concepts of bluntness and outgrowth were introduced to analyze powder sphericity and satellite index quantitatively. The results showed that the median diameters of all atomized powders ranged from... delivery tube diameter. Powders with bluntness values between 96% and 98% accounted for over 60%. The outgrowth values demonstrated that 70%-85% of all powders did not contain satellite particles......
