A moulded article is made from a composition comprising a mixture of 100 parts by weight ceramic fibres or a mixture of at least 20% by weight ceramic fibres and up to 80% by weight of a fired bonded granular material comprising ceramic fibres, bonding agent and refractory materials with 2 to 20 parts by weight clay and/or other conventional refractory materials, 0 to 8 parts by weight phosphate bonding agent, 0 to 10 parts by weight organic bonding agent, there being at least two parts by weight bonding agent present, with water. The mixture is compressed whilst being moulded into the desired shape and then dried and/or fired. The article has a density of 0.5 to 1.8 g/cm<3> and a hot bending strength at 1000 DEG C of at least 0.8 N/mm<2> |
