Description

Известен способ получени  арсенидов некоторых металлов непосредственным взаимодействием металлов с арсинами в эвакуированных кварцевых ампулах.A known method for producing arsenides of certain metals by direct interaction of metals with arsines in evacuated quartz ampoules.

Недостатком известного способа  вл етс  больша  длительность процесса и сложность аппаратурного оформлени .The disadvantage of this method is the long duration of the process and the complexity of instrumentation.

Предлагаетс  способ получени  арсенида галли  пропусканием арсина (мышь ковистого водорода) над окисью галли  при температуре 850-900°.A method for producing gallium arsenide by passing arsine (mouse of malleable hydrogen) over gallium oxide at a temperature of 850-900 ° is proposed.

Способ основан на реакции восстановлени  окиси галли  арсином по уравнению:The method is based on the reduction reaction of gallium oxide with arsine by the equation:

ОагОз + 2AsH3 2GaAs + ЗНгО,ОAGОЗ + 2AsH3 2GaAs + ЗНгО,

которое  вл етс  суммарным, так как реакци  проходит через стадии диссоциации арсина на атомарный водород и мышь к, восстановлени  окисла и образовани  арсенида.which is cumulative, since the reaction goes through the stages of dissociating arsine into atomic hydrogen and mouse, reducing oxide and forming arsenide.

Применение окиси галли  дл  получени  из него арсенида при взаимодействии с арсином не известно.The use of gallium oxide to obtain arsenide from it when interacting with arsine is not known.

Способ более производителен по сравнению с известным способом получени  арсенидов и технически более прост, что должно привести к определенному экономическому эффекту.The method is more productive as compared with the known method of obtaining arsenides and is technically simpler, which should lead to a certain economic effect.

Осуществление способа сводитс  к следующему.The implementation of the method is as follows.

Навеска порощка окиси галли  обрабатываетс  в течение 7 час трехкратным избытком газообразного арсина в нагреваемом до 850-900° кварцевом реакторе, из которого предварительно удал лс  в течение 10-15 мин воздух током аргона. Дл  более полного прохождени  процесса арсин разбавл ют водородом в соотношении 2:1.A charge of gallium oxide powder is processed for 7 hours with a three-fold excess of arsine gas in a quartz reactor heated to 850–900 °, from which air has been removed from the argon stream for 10–15 min. For a more complete process, the arsine is diluted with hydrogen in a 2: 1 ratio.

Выход продукта 99,8-99,9%.The product yield of 99.8-99.9%.

Полученный продукт, по данным химического анализа, соответствует формуле GaAs и, по данным фазового рентгеновского анализа, имеет решетку типа сфалерита с периодом 6,458А°- что близко к табличным данным (а 6,461 .4°).The resulting product, according to chemical analysis, corresponds to the GaAs formula and, according to phase X-ray analysis, has a sphalerite-type lattice with a period of 6.458 A °, which is close to the tabular data (a 6.461 .4 °).
