Abstract
A method of making a refractory article having excellent high-temperature thermal shock resistance and creep resistance is provided. The method includes the step of providing a refractory composition primarily composed of chamotte having controlled particle sizes. The refractory composition may also include mullite, fused silica, calcined alumina and microsilica having controlled particle sizes, and further includes an aqueous colloidal silica binder. The refractory composition is then formed into a refractory article, which is dried and hardened.
