Electric heating properties of FexOy–C composites
Tóm tắt
It has been established that during heat treatment of mixtures of waste activated sludge (WAS) and Fe2O3 under the conditions of oxygen deficiency at 800–1000 °C, reactive carbon, which initiates the reduction of Fe2O3 to Fe and the formation of C–FexOy mixtures, forms. Based on these compacted mixtures, having different electrical resistivity (from ~ 10–4 up to 10–1 Ω·m), it is possible to fabricate heating elements, whose working temperature ranges from ~ 100 °C up to 600 °C. Such heating elements can be used in the construction industry to accelerate the curing of concrete and its low temperature heating.
