Abstract
The invention discloses a gallium aluminum alloy and a manufacturing method thereof, wherein gallium in the gallium aluminum alloy according to percentage by weight is 15-85 percent, and after aluminum and the gallium are mixed according to the mixture ratio of 15-85 percent of gallium and are then molten in a vacuum heating furnace under the protection of an argon medium, the gallium aluminum alloy is prepared. The gallium aluminum alloy prepared by the method has even ingredients and no segregation phenomenon and can be slowly cooled to form particles of 0.5-10mm. The gallium aluminum alloy can be used for producing hydrogen while reacting with water.
Description
Technical field
The present invention relates to alloyed metal hydrogen manufacturing Application Areas, especially aluminium-gallium alloy and preparation method thereof.
Background technology
When water is contacted with aluminum gallium alloy, aluminium is by absorbing the oxygen water of decomposition, in this process, produce hydrogen, gallium is that inert does not participate in reaction, just because of the existence of gallium, has guaranteed the not oxidized formation pellumina of aluminium, thereby guaranteed activity, generate aluminum oxide and hydrogen with the water reaction, see reaction formula (I), hydrogen then can be used for fuel cell as hydrogen source.Because the fusing point of aluminum metal and gallium differs greatly, be 660.4 ℃ as the fusing point of metallic aluminium, and the fusing point of gallium is low to moderate 29.78 ℃, its alloy prior is very difficult.

Summary of the invention
The object of the present invention is to provide a kind of aluminum gallium alloy and manufacture method thereof.
The technical solution adopted for the present invention to solve the technical problems is: gallium accounts for the 85%-15% of weight alloy per-cent, and aluminium accounts for 15%85% of alloy.By said ratio with aluminium with after gallium mixes, under the protection of rare gas element such as argon medium,, promptly produce out aluminum gallium alloy through the vacuum furnace melting.Can adopt rapid cooling or slowly cool off and obtain the 0.5-10 mm granules.Vacuum furnace is a kind of in vacuum intermediate frequency furnace, vacuum arc fumace, the vacuum resistance furnace.
The purity of raw material aluminium is greater than 90% among the present invention, and the purity of raw material gallium is greater than 90%.
The invention has the beneficial effects as follows: the aluminium-gallium alloy that makes as stated above, the even segregation-free phenomenon of composition.Can be used for hydrogen manufacturing with the water reaction.
