Abstract

We study the influence of the intensity of constant external magnetic fields on the structure, thermal properties, and electric conductivity of composites based on ED-20 epoxy resin and one of the metal oxides (Al 2 O 3 or Fe 2 O 3 ). It is shown that, under the action of the magnetic field, the Fe 2 O 3 crystallites in the structure of the composite become finer (L ≈ 18 nm → 5.4 nm) and the densities of the initial epoxy polymer, the composites based on this polymer, and one of the metal oxides (Al 2 O 3 or Fe 2 O 3 ) increase, which, in turn, affects the other properties of these compounds, in particular, their specific heat and conductivity.
