Porous ceramics for application as high-temperature thermal insulators (600°C-1600°C) have been investigated as an alternative to the use of block and blankets of ceramic fibers. They present potential for such application because of the combination of low conductivity of porous structures (less than 5 W(m.K)-1 at 1200°C) with the refractoriness of ceramics. However, they do not resist densification as well as fibers after long periods at high temperatures. The presence of porosity reduces thermal conduction, because pores are filled with gases with low conductivity and also provoke scattering of photons, which are responsible for radiation process that occurs at high temperatures. To be effective it is also necessary that the pores be clos...
