Condensed silica fume - a by-product from silicon alloys industry is shown to be an interesting precursor to prepare highly porous, shaped ceramic articles. Compacts of silica fume of different green densities were sintered at 1000 °C. Thermal conductivity of received bodies ranges from 0.07 to 0.208 W m⁻¹ K⁻¹, the compression strength ranges from 1.2 to 53.0 MPa, respectively. |
