SiC-based refractory paints prepared with alkali aluminosilicate binders
Original language description
Refractory paints based on silicon carbide (SiC) were developed using inorganic alkali aluminosilicates binders. In order to optimize the binders, different raw materials have been tested for their preparations (calcined kaolin, commercial metakaolin, a-alumina and fumed silica synthetic powders). The alkali activator was an aqueous solution of KOH/K(2)SiO(3). The SiO(2):Al(2)O(3) molar ratio was equal to 4 and the SiO(2):K(2)O molar ratio was 2. Calcined kaolin and metakaolin in alkaline conditions dissolved and re-precipitated to form geopolymer resins acting as a glue for the un-reacted Al-Si materials and SIC (90 wt.%). Binders based on a-alumina and fumed silica behaved as water glass. Binders and SiC paints were tested and characterized in inertand oxidative atmospheres up to 1300 degrees C. The oxidation of the SiC paints was 50% lower than that of pure SiC, evidencing a key role of the alkali aluminosilicate binders during the thermal treatments.
