Technological aspects of producing multi-layer wicks with variable pore size, porosity and heat conductivity factor in radial direction from cheap and environmentally safe iron powder were studied. The mul-ti-layer structure serves the purpose of improvement of heat transporting characteristics of loop heat pipes. The capabilities of antisotropic wicks’ construction by means of layer-forming from powder fractions, distinguished in granulometric composition and concentration of oxygen in iron compound are being justified. Regularities of separate and joined pressings and sintering of thin-wall hollow cylinders are being studied and optimal parameters of the process providing for continuity of structure in transient areas between layers are being set. Efficiency of the technological approach designed is demonstrated on the example of production of two- and three-layer wicks that combine mono- and bidisperse layers of the capillary-porous materials with differing structural and skeleton properties. In wicks obtained, the heat conductivity factor at the absorbing surface is 0,3-0,4 W/(m - K), at the vaporization surface is 1,8-2,2 W/(m-K) with the corresponding porosity of 53-56 % and 70-75 % and pore radius of 1,3-1,5; 1,5-1,8 and 15-30 microns. The nontrivial combination of structural and skeleton properties is stipulated by excess 2,7-2,9 times concentration of iron oxides (FeO, Ре2О3, Fe3О4) in the inner layers of wick as compared to the outer, and not by morphology of the layer microstructure.
