    2002-5-3 · High Purity. High purity aluminas are normally classified as those with a purity of 99.99% and can be manufactured by routes starting from Bayer hydrate using successive activations and washings, or via a chloride to achieve the necessary degree of purity. Even higher purities are manufactured by calcining ammonium aluminium sulfate or from aluminium metal.
