New methods of developing volumetric ceramic articles using barium hexaferrite with chromium additives

The possibility of realizing the reaction of self-propagating high-temperature synthesis of ferrites, controlled by selective laser action, is shown. The conditions for the synthesis of barium hexaferrite with the addition of chromium and the effect of additional annealing on the synthesis result are investigated. The obtained bulk ceramic products have rather good consumer properties. Tab. 3, ill. 6, bibliography: 4 titles.
