Barium hexafemte doped with iridium was synthesized by two methods: the citrate gel and the polyacrylamide gel methods. The nature of phases obtained and the specific surface area were determined after heat treatments in air at 700°C, 900°C and in air containing 10% humidity at 1200°C. The catalytic activity in the combustion of methane was measured after heat treatment at 900°C. These hexaferr...

Three-dimensional printing is one of the most promising areas additive manufacturing with a constantly growing range applications. One current tasks development new functional materials that would allow manufacture objects defined magnetic, electrical, and other properties. In this work, composite magnetic filaments for 3D tunable properties were produced from polylactic acid thermoplastic poly...
