礬土和氧化鋁，除了鋁金屬以外，也作為阻燃劑和粗鋼，水力壓裂用的陶瓷支撐劑，Aluminosilicate glass(鋁矽酸鹽玻璃，也用於TFT液晶用基板)，ATH (氫氧化鋁) 等的原料。今後的非冶金用礬土、氧化鋁市場成長率，預計略低於全球GDP成長率，不過，其中陶瓷支撐劑、礦棉需求也預計大幅度成長。
The markets for both bauxite and alumina have experienced disruption of supply chains in recent years. Calcined bauxite was primarily sourced from China with Guyana, formerly the main source a distant second and other volumes from Brazil and India.
Chinese production has been restricted because of enforcement of environmental regulations resulting in the closure of many plants until they met environmental requirements or during the winter to reduce air pollution levels.
This restricted supply and caused prices to rise, at a time when demand from the refractories industry was strong. Additional supply from Guyana and to an extent from India and Brazil has been insufficient to replace the lost supply from China.
Alumina supply experienced significant disruption in 2018, with wide fluctuations in spot pricing, although most non-metallurgical trades are based on annual or longer term contracts.
The forced 50% reduction in output from the Alunorte operation in Brazil caused particular tightness in the ATH market in North America, which had become increasingly reliant on imports following the closure of two plants and alternative sources were sought to satisfy demand.
The threat of US sanctions against Rusal and a prolonged strike at some Australian alumina operations also contributed to widely fluctuating spot prices for alumina and restricted supply.
The supply problems are expected to have been largely resolved and outlook will be assessed in the report.
