I need this question to get solved step by step. Handwritten would be helpful
Consider the following phase diagram. What is the Tm of MgO and Al2O3? What is the Tm and overall concentration (C1) at the eutectic point between MgO and MgAl204? What is the concentration of the MgO and MgAl2O4 components for C1 at a temperature of 1800 degree C? How many grams of MgAI2O4 are in a 25g sample of C1 cast at 1800 degree C? Label the diagram with C2: 1600 degree C with an overall concentration of 30 wt% Al2O3. What is the other 70 wt% of C2? What is the concentration of the MgO and MgAI2O4 components in C2? What is the weight fraction (in %) of eutectic components and primary MgO components at 1600 degree C?
