Hi:
I am considering a possible commercial application where the starting material is either pure (defined as over 95%) Al or Al2O3 and other lower cost ingredients.
My limited research indicates that pure Al2O3 is much more expensive than pure Aluminum.
Is this correct? Or a quantity of ordering problem, or the higher associated cost of creating pure Al2O3, or a bad supplier for Al2O3?
Thanks for any help.
