METHOD FOR OBTAINING COMPACT MATERIALS CONTAINING TITANIUM DIBORIDE USING SELF-PROPAGATING HIGH-TEMPERATURE SYNTHESIS Russian patent published in 2018 - IPC C22C29/14 B22F3/23 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to the production of compact materials containing titanium diboride using self-propagating high-temperature synthesis (SHS). Embodiment 1 of the method comprises preparing the reaction mixture from powdered ferroboron and ferrotitanium, compacting the reaction mixture, and initiating the SHS. Ferrotitanium is used with a titanium content of at least 60 % by weight, as well as ferroboron with a boron content of not less than 6 % by weight, wherein the reaction mixture is prepared with a ratio of the mass of ferrotitanium to the mass of the ferroboron from 0.1 to 0.8 and a glue binder in an amount not exceeding 40 % by weight of the reaction mixture is added to the reaction mixture. In embodiment 2 of the method, dopants in the amount of up to 80 % by weight of the reaction mixture are added to the reaction mixture, as well as the glue binder in an amount not exceeding 40 % by weight of the reaction mixture.

EFFECT: method ensures the production of compact materials containing titanium diboride, without the use of special reactors and the application of external actions on the reaction mixture during the synthesis.
