Název v původním jazyce

Alkali-bonded ceramics with hierarchical tailored porosity

Popis výsledku v původním jazyce

Alkali-bonded ceramics and foams with tailored porosity have very interesting applications as thermal insulators, catalysts, filters, etc. Alkali-bonded ceramics were prepared starting from metakaolin and potassium silicate, selecting the process conditions, to change the intrinsic nano-micro-porosity of the geopolymer, and studying their influence on the degree of geopolymerization. Optimum geopolymerization conditions were chosen to develop porous 3D networks by inducing interconnected ultramacroporosity (up to the millimetre range) in the material, exploiting the ability of silicon powder to generate H-2 in the reaction environment. The in situ foaming was strongly dependent on the water content of the geopolymeric precursors and the subsequent process of water elimination. The H-2 formation is, in fact, a water-consuming process, just as consolidation is, thus increasing the viscosity. The geopolymeric inorganic matrices and the related foams were fully characterized in terms of mi
