Spontaneous Polarization of Hydrogen-Saturated Composite Materials

  • Published:
Russian Physics Journal Aims and scope

The paper focuses on the effect of spontaneous electric field emergence in mixtures of cesium nitrate and/or potassium permanganate microparticles with nickel, aluminum and aluminum oxide nanoparticles in the hydrogen atmosphere. It was established that increase in the share of Ni, Al or Al2O3 nanoparticles in the mix with KMnO4 powder from 0 to 0.25 (in terms of weight) leads to gradual decrease in electric field density in the powder to zero (T = 22–250°C). The authors identified the stimulating effect of nickel nanoparticles on hydrogen-initiated electric field emergence in the CsNO3 powder. It was established that spontaneous polarization of powders is caused by dissociative chemisorption of hydrogen molecules on the surface of KMnO4 and CsNO3 particles.
