通常的铝的化合物都是三价铝化合物。但在近十年来,陆续发现了许多一价铝化合物,即亚铝化合物。许多三价铝化合物和铝一同加热,就生成亚铝化合物,例如: 4Al+Al_2O_3→←3Al_2O 4Al+Al_2S_3→←3Al_2S 4Al+AlX_3→←3AlX(X=Cl,Br,I,F) 迄今发现的亚铝化合物有氧化亚铝、硫化亚铝、硒化亚铝、和亚铝的卤素化物等七种。它们多成气态存在,冷时分解,凝集出金属铝和三价铝化合物。
The usual aluminum compounds are trivalent aluminum compounds. However, in the past ten years, many monovalent aluminum compounds have been discovered, namely, aluminum compounds. Many of the trivalent aluminum compounds are heated with aluminum to form an aluminum compound such as 4Al + Al_2O_3 → ← 3Al_2O 4Al + Al_2S_3 → ← 3Al_2S 4Al + AlX_3 → ← 3AlX (X = Cl, Br, I, F) Aluminum compounds include aluminum oxide, aluminum sulphide, aluminum selenide, and halogenated compounds of aluminum and aluminum. They are mostly gaseous, decomposed when cold, agglomeration of aluminum and trivalent aluminum compounds.
