Abstract: A ceramic fiber is prepared without the need for a fiber-forming organic polymer or a coagulating bath by forming a homogeneous clear solution from an aluminum halohydrate organic complex dissolved in a mixture of water and a C1-C4 alcohol from which a clear homogeneous precursor filament is drawn and fired, which complex is obtained from an aluminum halohydrate and a polyol containing 2 to 6 carbon atoms and at least 2 hydroxy groups.

Abstract: The invention relates to the insulating of furnace walls with a double layer of insulating modules of the type having refractory fibers disposed end on to the oven wall when disposed in place. The modules are first compressed and held that way with easily combustible material and the compression released during the firing of the furnace to destroy the wrapping material. The first layer is preferably non-aligned with the second layer to limit the loss of insulation due to aligned seams.
