摘要：

The paper presents the experimental device for obtaining glass microspheres in rotating electrical are. With this device, for are power values of 5 x 10(3) W and for frequency of v = 850 s(-1), the glass powder with arbitrary shaped particles was transformed in microsphere with diameters between 2 and 24 mu m and the wall thickness between 0.4 and 1.6 mu m. The particles in the powder were up to 30 mu m in diameters, have a flow rate of 2 g.min(-1) and were transported in argon (5 Nl min(-1)). The mean diameter is (d) over bar = 5.62 mu m.
