The second paragraph says that to avoid the question of how many waters are usually associated, some people write "Al_{2}O_{3} \cdot xH_{2}O." Unless I'm very much mistaken, that's the formula for a hydrate of aluminium oxide. The proper formula for aluminium hydroxide is Al(OH)3, as is listed in the column to the right.

If I don't get any objections by June 25, I'll change that.---WilliamRobert

Read it again, the Al(OH)3 is there several times in the text. The xH2O bit is there as a general usage to avoid the controversy/confusion on the various forms - technically incorrect, but seems the chemistry is confusing as reported. Vsmith 01:32, 21 June 2006 (UTC)


Hmm. The article should probably mention the fact that when heated (calcined), aluminum hydroxide forms aluminum oxide, as in the Bayer Process. I think that simply referring to the Bayer Process is insufficient. -Anon
