METHOD OF PRODUCING CERAMIC POWDER MATERIAL BASED ON MAGNESIUM NITRIDE BORIDE (MgNB) Russian patent published in 2025 - IPC C04B35/58 C04B35/65 C04B35/626 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing magnesium nitridoboride (MgNB₉) and composites based thereon. MgNB₉ can be used in short-wave optoelectronics and high-temperature, high-power and high-frequency electronic devices. Method of producing ceramic powder material based on magnesium nitride-boride (MgNB₉), involving preparation of a reaction mixture consisting of powders of magnesium and boron in molar ratio of components Mg:B equal to 1/9 ≤ Mg/B ≤ 3.6/9, synthesis under effect of temperature and gas pressure. Prepared mixture is placed in a reactor, synthesis is carried out in combustion mode in a nitrogen atmosphere at nitrogen pressure 0.5 < P_N2 < 6.0 MPa.

EFFECT: disclosed method enables to obtain ceramic powder material based on magnesium nitride boride MgNB₉ with low operating costs, including without electric power consumption for heating the reaction mixture.
