  • Experimental Investigation of Pressure Drop Through ...

    Real ceramic foams have varying percentage of pores that are blocked. This is the effect of fabrication process, and the percentage of clogged pores increases with number of pores per inch. The resistance to the flow was expected to be higher in the structures with higher number of blocked pores.In figure 1 a real geometry and its virtual ...

  • Alumina-Silica Type AX Moldable – ZIRCAR Ceramics,

    ZIRCAR Ceramics’ Alumina-Silica Type AX Moldables are putty-like materials consisting of high-purity refractory ceramic fibers (RCF) dispersed in a sticky, water-based refractory binder. AX Moldables exhibit excellent adhesion and insulation properties and are characterized by their high strength, low shrinkage, and low thermal conductivity up to 1260°C (2300°F). Type AX Moldable is useful ...

    2014-2-18 · It has been a long-standing effort to create materials with low density but high strength. Technical foams are very light, but compared with bulk materials, their strength is quite low because of their random structure. Natural lightweight materials, such as bone, are cellular solids with optimized architecture. They are structured hierarchically and actually consist of nanometer-size building ...
