| Summary: | Abstract The work considers the regularities of SHS of ferrotitanium, ferrochromium and synthetic mica-based fluorophlogopite. The powder mixture of minerals (silica sand, Karelian shungite, ilmenite, chromium concentrate from Shorzha) and secondary raw materials (recirculated cryolite) with metal reducing agents and KClO 4 energy additive were used for the synthesis. The regularities of the initial mixture combustion under atmospheric conditions, the synthesized product composition and structure were investigated. Low-carbon ferrochromium with carbon content of 0.2%, ferrotitanium of the composition close to that of the industrial FeTi30 and synthetic mica-fluorophlogopite were synthesized. The synthesis of porous and molten-cast materials based on fluorophlogopite is shown to be possible. The composite material of K(Na)Mg 3 AlSi 3 O 10 Fe 2 -MgAl 2 O 4 -SiC was synthesized. |
