Abstract
The invention provides a porous refractory ceramic material having a high surface area per unit volume, a high resistance to sudden temperature variations and a low resistance to fluid flow. The material is a ceramic replica of a body of reticulated organic foam in which the ceramic consists essentially of fibrous material. Any non-fibrous particulate matter present is in an amount which makes no significant contribution to the strength of the body. The material is made by impregnating a body of reticulated organic foam with a slurry of finely-divided inorganic fibres, and drying and firing the thus -impregnated body. The material is of value as a catalyst support and as a facing element of burner assemblies.
