The commercial silica sol-bonded compositions showed higher strength due to its higher solid content but resulted in inferior hot and corrosion properties. The slag corrosion resistance was also observed better for the spinel sol-containing composition. Improved thermal shock resistance against commercial sol binder was observed in spinel and mullite sol-containing compositions, which may be associated with the microcracking effect produced from the thermal expansion mismatch. Mullite sol-bonded composition showed higher cold strength, whereas spinel sol resulted in better hot properties. These developed sol-containing compositions were also compared against commercially available silica sol-containing composition prepared under exactly similar conditions. The castable compositions were processed conventionally and properties were evaluated after heat treatment at different temperatures. Four different sol systems, namely, alumina, boehmite, mullite, and spinel, have been synthesized and used individually as sole binder in high alumina castable system with particle size distribution coefficient of 0.23 as per Dinger and Funk model. A comparison among various sol-gel bonding systems has been done for high alumina castable refractory.
