%X The size and shape of a-Al2O3 particles may be controlled in the preparation of a-Al2O3 ultrafines by a-Al2O3, a-Fe2O3 seeding in wet-chemical methods, which can increase the transformation rates and reduce the activation energy for the phase transformation. Therefore, the cost for the preparation of a-Al2O3 ultrafines by the hydrothermal method is reduced greatly. The research works at home and abroad have been summarized, and the effects of seed crystals on preparation of a-Al2O3 ultrafines by wet-chemical methods have been summarized combined with the authors research.
