A method of making a refractory material, such as for furnace use, from refractory fibres and a polymeric binder which burns or otherwise degrades to allow the fibres to expand from a pre-compressed state, comprises the steps of preparing a highly dispersed aqueous suspension of the fibres, adding 2-10% by weight of the binder in aqueous suspension, adding a coagulent for the binder, forming a compressed felt body by extraction of the water, such as by suction-forming, and drying the felt body whilst maintaining its compressed state. |
