MgO-bricks are often produced with a mixture of carbon and silicon as binder material.
- Up to which temperature will the brick only exhibit condensed phases?
- What composition has the gas phase, when the brick begins to show volatilization?
The figures show the results of a complex equilibrium calculation with ChemSage.
- Figure 1: Above 2040 K carbon is volatilized from the binder and the brick begins to disintegrate.
- Figure 2: The gas evolved consists mainly of magnesium and carbon monoxide.
