### Thermal conductivity of highly porous mullite

2013-12-1 · The thermal conductivity of air and dense mullite ceramic were chosen to be 0.026 and 5.1 W/m K from literature values , . Fig. 6 shows the influence of porosity on the thermal conductivity of porous mullite materials, compared with the predicted curves based on the Series and Parallel models, Maxwell–Eucken models and EMT equation.
