Notes:
The silica-alumina sol bonding agent, prepared by the sol gel route from ethyl silicate andaluminium isopropanol, was utilized in the refractory castables. The influence of structure on the heattransfer has been investigated using different sorts of refractory matrix. The results indicated that theheat conductivity of sol-gel bonded castables was considerably affected by their structure. The phasecomposition of matrix, porosity, pore size distribution and pore size structure were the most importantfactors. Thermal conductivity has been measured from the ambient temperature up to 1250 °C. Theinfluence of crystalline phases and the glassy phase formation and the influence of the pore sizedistribution on the thermal conductivity were also described in this work
