Hi,although i'm not a metallurgical engineer i think there is a difference between high purity aluminium and high purity alumina. Aluminium is a good conductor of electricity whereas alumina is an isolator. In the brochure attached Hydro seems to be a producer of high purity aluminium and high purity alumina but the main product is high purity aluminium.
I haven't spent too much time researching the subject but probably they're not mentioned because they don't produce significany quantities of High Purity Alumina.
My 2 cents.

yes there is a difference. look into the brochure from hydro which i posted. at the last pages (from page 10) you can see some sapphire crystals and the application it is used for. so they produce 4N and 5N HPA from high purity aluminium. but iam not sure in wich quantity. probably it isnt a large amount. but i cant verify. probably the larger amount is high purity aluminium and not alumina. but i dont know it.
