Abstract
A refractory composition yields refractory articles having excellent resistance to high-temperature thermal shock and creep. The refractory composition is based primarily on chamotte having controlled particle sizes, and may also include mullite, fused silica, calcined alumina and microsilica, having controlled particle sizes. The refractory composition includes an aqueous colloidal silica binder that provides excellent castability and binding between the ingredients following drying.
