The purity of rare earth modified alumina in 2018 is greater than 99.999%

    Precision is one of the core indicators of modern equipment manufacturing, and purity is the most important indicator in the field of new materials research. Purity often determines the success or failure of research and development. As the so-called difference is far away, purification technology has been the goal of many researchers. The editor of Chain Technology today learned of another technology that China has reached the top. The rare earth modified high-purity sapphire raw material pilot project independently developed by the R&D team of the School of Materials Science and Engineering of Shanghai Jiaotong University was officially put into production. The production line produced 5N (purity greater than 99.999%) high-purity alumina products for the first time. High-purity alumina is a high-end product in the aluminum industry and the main raw material for artificial sapphire. The new project fills up the gap in the international rare earth high-purity aluminum preparation technology, and will also enable the high-purity aluminum industry chain and the artificial sapphire industry chain to be fully integrated.
