Abstract
Se describe una estructura de oxido de hierro monolíticas de pared delgadas y proceso para formar dicha estructura. La estructura comprende una estructura de oxido de hierro monolítica obtenida de la oxidacion de una estructura que contiene hierro, preferiblemente acero simple, de pared delgada, a una temperatura por debajo del punto de fusion del hierro. El grosor preferido de la pared del acero es menor que aproximadamente 0.33 m. Los oxidos de hierro preferidos de la invencion son hematita, magnetita y sus combinaciones. Las estructuras de pared delgada de la invencion substancialmente tienen la misma forma física que la estructura de partida de hierro las estructuras de oxido de hierro de pared delgada de la invencion, se pueden usar en una amplia variedad de aplicaciones, incluyendo divisores de flujo de gas y líquido, componentes resistentes a la corrosion de sistemas de escape automotrices, soportes catalíticos, filtros, materiales de aislamiento térmico y materiales aislantes de sonido. Los oxidos de hierro de la invencion que consisten substancialmente de magnetita, se pueden calentar eléctricamente y, por lo tanto, pueden ser aplicables en aplicaciones tales como aislamiento térmico calentado eléctricamente, calentamiento eléctrico de líquidos y gases que pasan a través de canales y dispositivos incandescentes. Adicionalmente, se pueden fabricar las estructuras de combinacion que usan tanto magnetita como hematita.
