Claims (2)

1. Способ повышения термической устойчивости гидрида алюминия при хранении, заключающийся в контактировании его перед закладкой на хранение с пропиточным химически активным веществом при температуре не выше температуры начала термического разложения гидрида алюминия, отличающийся тем, что для гидрида алюминия, содержащего протий, в качестве химически активного вещества используют воздух или его химически активные компоненты, а контактирование проводят при температуре не выше 343 К в течение времени, определяемого выражением е-17,1 +5445/T≅t≅е-14,1 +6386/T, где t - время контактирования в часах и Т - температура в кельвинах.1. A method of increasing the thermal stability of aluminum hydride during storage, which consists of contacting it before storing it with an impregnating chemically active substance at a temperature not higher than the temperature of the onset of thermal decomposition of aluminum hydride, characterized in that for aluminum hydride containing protium, as a chemically active substance is air or its reactive components, and the contacting is conducted at a temperature not exceeding 343 K for a time determined by the expression e -17.1 + 5445 / T t≅e -14.1 + 6386 / T, where t - the contact time in hours and T - the temperature in Kelvin. 2. Способ повышения термической устойчивости гидрида алюминия при хранении, заключающийся в контактировании его перед закладкой на хранение с пропиточным химически активным веществом при температуре не выше температуры начала термического разложения гидрида алюминия, отличающийся тем, что для гидрида алюминия, содержащего дейтерий, в качестве химически активного вещества используют воздух или его химически активные компоненты, а контактирование проводят при температуре не выше 368 К в течение времени, определяемого выражением е-20,6+ 7240/T≅t≅e-5,5+ 4010/T, где t - время контактирования в часах и Т - температура в кельвинах.2. A method of increasing the thermal stability of aluminum hydride during storage, which consists of contacting it before storing it with an impregnating chemically active substance at a temperature not higher than the temperature of the onset of thermal decomposition of aluminum hydride, characterized in that for aluminum hydride containing deuterium, it is chemically active substances use air or its chemically active components, and contacting is carried out at a temperature not exceeding 368 K for a time determined by the expression e -20.6 + 7240 / T ≅t≅e -5.5+ 4010 / T , where t is the contact time in hours and T is the temperature in kelvins.
