1) Using the Al2O3 – SiO2 phase diagram (Figure 12.25) as a reference, which material would be considered as the more desirable refractory, 90 wt% Al2O3-10 wt% SiO2 and 18 wt% Al2O3-82 wt% SiO2? a) 90 wt% Al2O3-10 wt% SiO2 is the more desirable refractory. b) 18 wt% Al2O3-82 wt% SiO2 is the more desirable refractory. c) Both are about the same A technique for constructing a phase diagram of the CaO-Al2O3-SiO2 system on a computer using the kinematic approach to describe surfaces is proposed. The geometric structure of the diagram and ...

Fig 1 SiO2 – Al2O3 phase diagram. As seen in the diagram, refractoriness increases with the increase in the Al2O3 content. The eutectic at 1595 deg C has a composition of 94.5 % SiO2 and 5.5 % Al2O3. As the Al2O3 content is increased, the melting point of the refractory increases to a maximum of 2054 deg C which is the melting point of pure ...
