內容簡介

Mega trends like urbanization, industrialization and growing population drive the demand of daily necessaries and therefore result in increased refractory consumption for waste treatment carried out at elevated temperatures. It is estimated that for burning 1 t of waste about 5.5 kg of refractory materials need to be consumed. In the present study, the corrosion resistance of refractory bricks based on alumina-chromia and alumina-silica was tested by exposing them to slag from hazardous waste incineration. Samples from the cup test were investigated macroscopically and mineralogically. They showed that alumina-chromia bricks had high corrosion resistance when in contact with the tested slags, while aluminasilica bricks containing silicon carbide showed an overall good performance.
