Abstract
Proceso para reducir cromo hexavalente en sólidos oxídicos, que comprende los pasos de: a) calentar el sólido oxídico que contiene Cr(VI) a una temperatura de desde 600 a 1400ºC en una atmósfera que contiene menos del 0,1% en volumen de un gas oxidante y b) enfriar el producto de reacción obtenido luego del paso a) a una temperatura por debajo de 100ºC en una atmósfera que contiene menos del 0,1% en volumen de un gas oxidante, caracterizado por que no se agrega ningún agente reductor al sólido oxídico o a la atmósfera en los pasos a) y b) del proceso.
