The percolative conduction in a three-dimensional case was investigated for bulkspecimens of Nb-alumina composites, where the dimensional crossover does not takeplace. The volume-fraction f of Nb ranges from 0 to about 0.9. 'The percolation transiLion was found to occur around /=0.15. This threshold value.( implies a highly random structure of the composite. Such occurrence of the percolation transition andthe behavior of the conductivity o' were described by an effective medium model interms of an aggregation of the complex cells which can be regarded as structuralelements of the networklike jcercolation cluster. 'The power law o'cl(f -/.)" wasfound to hold over the entire range /.<,7'<1 with 31 critical exponent q=2.06f0.05,which closely approximates to the estimation given by the existing models.[percolation, niobium-alumina composite, sinter, cluster, coxnplex cells, effective l9 medium, critical exponent of conductivityl
