Properties： It is a white crystal or powder with relative density of 2.882(25℃). It is insoluble in most organic solvents, hydrofluoric acid and liquid HF. It is stable, even doesn't react with liquid ammonia and concentrated sulfuric acid by heating to fuming, isn't changeable when co-melted with KOH and can't be reduced by hydrogen. It doesn't decompose through heating, but sublime. The sublimation temperature is 1291℃. It decomposes partly to HF and aluminium oxide at 300-400℃. It is toxic.[...]
