METHOD FOR PRODUCING ALUMINIUM HYDRIDE Russian patent published in 2024 - IPC C01B6/06 C01F7/00 B01J19/12 

FIELD: various technological processes.

SUBSTANCE: invention can be used to produce aluminium hydride, which is used as an energy component of fuel cells, solid rocket propellants and in hydrogen accumulators. Method of producing aluminium hydride involves using a linear electric arc evaporator. Initially, the main part of air from the vacuum chamber is removed by a foreline pump to pressure of 1–3 Pa. Simultaneously with air pumping, reels of organic film are rewound. Further, the chamber is pumped with argon at pressure of 50 Pa for 3–5 minutes. Argon is then fed through argon feed tubes. Hydrogen is supplied through hydrogen supply tubes and pressure is brought to 300 Pa, and initial ignition of arc is performed on aluminium cathode by supply of high voltage. Microwave magnetron is used to create a high-frequency electromagnetic field which induces a plasma discharge in the gas mixture. Further, under non-equilibrium plasma conditions, reactions occur between aluminium ions and hydrogen ions, which leads to formation of aluminium hydride.

EFFECT: invention simplifies production of stoichiometric aluminium hydride, increases its output and improves stabilization of the synthesis product.
