Abstract
A presente invenção refere-se a uma lama vermelha modificada ou a um resíduo de bauxita modificado, assim como processos para sua produção e um meio acumulador, que compreende uma lama vermelha modificada, um acumulador de calor, que compreende um meio acumulador e inúmeros usos de uma lama vermelha modificada como um meio acumulador, em particular, em um acumulador de calor. Neste caso, a lama vermelha modificada contém os seguintes componentes: - hematita (Fe2O3), - córundo (Al2O3), - rutila (TiO2) e/ou anatas (TiO2), - quartzo (SiO2), - opcionalmente perowskita (CaTiO3) e ? opcionalmente pseudobrookita ((Fe3+, Fe2+)2(Ti,Fe3+)O5), nefelina ((Na,K)[AISiO4]) e/ou hauinita ((Na,Ca)4-8[Al6Si6O24(SO4)], sendo que a lama vermelha modificada é essencialmente livre de Na2O e/ou vidro. Por esse meio, um novo material é posto à disposição, assim com sua produção para aplicação como meio acumulador no sistema sensível de acumulação de energia na faixa baixa, média e alta de temperatura.
