Jan 27, 2011 · However, due to it being for a medical application we cannot use aluminium oxide. This is why I was asking about testing for aluminium oxide and removing aluminium oxide. It appears as though there will still be traces of aluminium oxide whatever we do to the samples, so it doesn't look like we will be able to use aluminium oxide at all.

The smaller difference means that the bond won't be so purely ionic. It is also likely that molten aluminium oxide contains complex ions containing both aluminium and oxygen rather than simple aluminium and oxide ions. All this means, of course, that you aren't really comparing like with like - so wouldn't necessarily expect a neat trend.

Oct 23, 2020 · Occurrence and history.
