METHOD FOR PRODUCING HOLLOW MICROSPHERES OF METAL OXIDES

摘要: FIELD: manufacturing technology.SUBSTANCE: invention relates to the production of hollow microspheres. Method for producing microspheres metal oxides includes preliminary preparation initial oxide powder and size-based classification resultant powder, sequential loading one isolated fractions into a dispenser, melting spheroidization in flow low-temperature plasmatron plasma torch, cooling formed product its size with determination bulk weight finished During torch length is maintained range 600–1,200 mm, at feed rate fraction 5–18 kg/h, plasma-forming nitrogen gas 0.45–0.85 g/s supply power 45–80 kW.EFFECT: ceramic optimal quality.3 cl, 6 tbl
