Theses and Dissertations
The main goal of this research is to develop high strength high toughness nano-ZrO2 reinforced self flow low cement (5%) and ultra low cement (3 and 1%) castables based on tabular alumina. In processing these castables, the Andreassen model was used to obtain optimum self flow properties in both, low and ultra low castables. The castables thus produced were fired at 110 and 1000, 1300 and 1500oC and the phases obtained were investigated by X-ray diffraction (XRD) including energy dispersive X-ray (EDX), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). In addition, the other castable properties …
