FIELD: technology of production of finely-porous membranes; medicine, chemistry and other industries.
SUBSTANCE: proposed method includes grinding of wire by pulse discharge followed by burning nano-dispersed electrically explosive powder in air, grinding and introduction into charge in the amount of from 1 to 10%. Roasting is performed at rate not exceeding 60°/h to temperature of 1000°C and then to sintering point at rate not exceeding 80°/h. Proposed method ensures facilitated procedure for production of non-shrinkable ceramic membrane filters at permeating porosity and average size of pores of 0.1 mcm and lesser.
EFFECT: facilitated procedure; enhanced efficiency.
