摘　　要：研究了球磨时间对所制备NiFe2O4-10NiO基镍铁尖晶石的微观形貌、体积密度、气孔率、抗热震性、抗腐蚀性的影响。研究结果表明球磨时间对惰性阳极的性能影响很大。当球磨时间为6h时,试样的体积密度最大,气孔率最小,抗腐蚀性最强,提高了球磨效率,但由于体积密度大,增大了试样的脆性,其抗热震性较差。综合试样各方面的性能,确定最佳球磨时间为6h。The effects of milling time on microstructure, volume density, porosity, thermal shock resistance and corrosion resistance of inert anodes of NiFe2O4-10NiO effects on properties of inert anodes. When the milling time were studied. The results show that milling time has great is 6 h, the density is maximum increased and the porosity is minimum increased, the corrosion resistance is the best, which improves the ball mill efficiency, but because of the vo lume density, the brittleness increased, which lead to its thermal shock resistance poor. Considering all aspects of performance,the optimal milling time is 6 h.
