摘要： Process for the production of refractory shapes of ceramic fiber-containing mateial, wherein a slurry of refractory fibers and particulate refractory materials is produced in water, the particulate refractory materials are flocculated on the fibers by use of a flocculant, and the desired shape is produced by dewatering the slurry in a suitable mold that enables the water to be removed, and the shape is dried. At least 90% of the fibers have a maximum length of not more than 500 .mu.m; flocculant is added as an aqueous solution to the dispersion of the fibers and particulate refractory material; and pressure is applied to the shape being formed during the dewatering of the slurry to form the desired shape in order to compress the shape.
