Description
Summary:Present paper considers processes of production and treatment of hollow particles in plasma flows. Specifics of agglomerated powders treatment and expansion of hollow droplets are analyzed theoretically. Experimental results on production of hollow micro particles of ZrO2, Ni, CoNiCrAlY alloy, SiO2 are shown here.
