AlSb can be alloyed with other III-V materials to produce the following ternary materials: [[aluminium indium antimonide|AlInSb]], [[AlGaSb]] and [[AlAsSb]].
AlSb can be [[chemical reaction|reacted]] with other III-V materials to produce ternary materials including [[aluminium indium antimonide|AlInSb]], [[AlGaSb]] and [[AlAsSb]].


Aluminum antimonide is rather flammable because of the reducing tendency of the antimonide (Sb<sup>3-</sup>) ion. It burns to produce [[aluminum oxide]] and [[antimony trioxide]].
