Dimensional effect in percolation processes

Conclusions Analysis of the geometrical special features of the sintered granular systems with large differences in the particle size of the components makes it possible to explain, to a first approximation, the experimentally detected dimensional effects of resistance variations.The proposed method of analytical evaluation of the variation of resistance can be used for predicting the nature and scale of the expected effects in a wide range of the variation of the determining parameters with the accuracy ± (20–25)% which is comparable with the scatter of the experimental data caused by fluctuations of the determining parameters in processing (by the particle size of the conductor and the insulator, residual porosity, the properties of the initial components and percolation parameters x_c, t).Translated from Poroshkovaya Metallurgiya, No. 7(283), pp. 64–71, July, 1986.
