Abstract
The disclosure relates to an inorganic, halogen-free flameproofing agent produced from modified, recarbonized red mud (MKRS-HT). The agent may have a mineral composition of 10 to 50 weight % of iron compounds, 12 to 35 weight % of aluminum compounds, 5 to 17 weight % of silicon compounds, 2 to 10 weight % of titanium dioxide, 0.5 to 6 weight % of calcium compounds the weight ratio of Fe (II) carbonate to the oxides of iron being at least 1. The agent, according to examples, can be used as a flame retardant in the high-temperature range. The disclosure further relates to flameproofing agent produced from modified, recarbonized and rehydrated red mud, which may be a flame retardant in the low-temperature range as well as in the high-temperature range, methods for producing same and use as flame retardants, substitutes, synergists, thermal stabilizers, heat accumulators, heat insulators and/or sound insulators and/or as electromagnetic radiation shielding materials.
