Vaporization of One Solid Reactant

The carbothermic reduction of silica is believed to follow [25] a reaction mechanism given by 

Chapter 5 Ceramic Powder Synthesis with Solid Phase Reactant 

FIGURE 5.16 Free energy change for carbothermic reduction of Si02 as a function of temperature and pressvire. From Kvork an et al. [26]. 

As another example, we look at the carbothermic reduction of tungsten oxide, which follows a reaction mechanism 

Yet another example of the vaporization of a solid is shown in the following reaction mechanism [24]
