Композиция, содержащая модифицированный красный шлам с низким содержанием хроматов, и способ ее получения
The present invention relates to a modified red mud/a modified bauxite residue and also to processes for the production thereof and to a storage medium comprising a modified red mud, to a heat storage means comprising a storage medium and to numerous uses of a modified red mud as storage medium, in particular in a heat storage means. The modified red mud contains the following components: haematite (Fe2O3), —corundum (Al2O3), —rutile (TiO2) and/or anatase (TiO2), —quartz (SiO2), —optionally perowskite (CaTiO3) and —optionally pseudobrookite ((Fe3+,Fe2+)2(Ti,Fe3+)O5), nepheline ((Na,K)[AlSiO4]) and/or hauynite ((Na,Ca)4-8[Al6Si6O24(SO4)]), wherein the modified red mud is substantially free from Na2O and/or glass. A novel material is thus provided, and the production thereof for use as a storage medium in a sensitive energy storage system in the low-, medium- or high-temperature range is described.
