Abstract
The relation between the microstructure and the macroscopic conductivity of Ti-Al2O3 cermet is analysed by using percolation theory. It is found that the result of percolation model is consistent with experimental result. The percolation threshold ω* the critical percent content of Ti-Al2O3 cermet is 0.16, and critical exponents are the same as those of three-dimensional continuous percolation.
