• Resumen

  • Calcined alumina can be used directly in refractory applications, as well as a feedstock to produce higher grade alumina products (for example, tabular alumina). Demand for calcined alumina was expected to be around 2.8m in 2013, according to market sources and roughly equal to levels in 2012. Of this number, approximately 20% was intended for WFA, 16% for tabular alumina and 19% for refractories.

    Tabular alumina, so called because the end-product of the sintered alumina balls resemble tablets, has seen a rise in demand over 2012, according to China's Zhejiang Zili. Zili intends to be the world's largest tabular alumina producer, a position currently held by Almatis. Other producers include Alteo, Japan's Naigai and Slovenia's Alusil.

    "Between 600,000 and 700,000 tonnes of alumina a year are used in flame retardants", [Johannes Heckmann], board director at Nabaltec, told IM.
