A fibrous ceramic mat is molded from a slurry of ceramic fibers and/or ceramic micropartides and/or a metal. The mat is impregnated with a sol prior to drying. A catalyst for the sol is introduced into the mat to cause the sol to gel. The sol-gel binder forms bonds so that the mat is dimensionally stabilized. The mat is dried to produce the desired ceramic insulation that has preferably a consistent microstructure and a fully gelled sol-gel binder through its entire thickness. If we use a metal, it corrodes (i.e., oxidizes) or otherwise reacts to form a refractory binder that augments the sol and reduces the need to infuse sol incrementally to achieve strength. Using metal powder significantly reduces the cost of manufacture. |

A ceramic fiber insulation material is disclosed. It is prepared from a precursor blend generally comprising a gelled colloid and a ceramic fiber filler. Other filler, e.g., other fiber of refractory material, is contemplated, particularly when mixed with ceramic fiber. The gelled colloid ban be formed such as by mixing a gelling agent with a colloid of inorganic oxide or by blending anionic colloid with cationic colloid. The gelling agent is typically nonionic and water-soluble. The blend is trowelable, pumpable and possesses excellent adhesive characteristics including the ability to stick to most surfaces, including metal surfaces. The blend is also virtually shrink-free during drying and, after drying, can provide the insulation material. |

A slurry is molded from ceramic fibers and/or microparticles to form a soft felt mat which is impregnated with a sol prior to drying the mat. A catalyst for the sol is caused to diffuse into the mat by exposing the mat to the catalyst and subjecting the mat to a soak time during which the catalyst diffuses into the mat and causes the sol to gel. The sol-gel binder forms bonds so that the mat is dimensionally stabilized. The mat is dried to produce ceramic insulation.Ceramic insulation having a consistent microstructure and a fully gelled sol-gel binder through its entire thickness is also provided. |

A precursor, in gel form, of an oxide having the formula (I), BaO.n(Al.sub.2x Cr.sub.2y O.sub.3), where 1.ltoreq.n.ltoreq.6.6, (x+y)=1, and 0.ltoreq.y.ltoreq.0.5, said oxide being derivable from the precursor gel by the application of heat, is prepared by mixing a solution of a barium salt with a solution of an aluminium salt or a solution of an aluminium salt and a solution of a chromium salt, and polymerising the mixture to produce said precursor gel. A mixture suitable for firing to an oxide of the formula (II), BaO.m(Al.sub.2x Cr.sub.2y O.sub.3), where 4.6.ltoreq.m.ltoreq.6.6; (x+y)=1; and 0.ltoreq.y.ltoreq.0.5, comprises at least one of: (a) barium oxide; (b) a clean thermal precursor of barium oxide; and (c) barium mono-aluminate, BaO.Al.sub.2 O.sub.3 ; with at least one of: (A) alumina, Al.sub.2 O.sub.3 ; (B) hydrated forms of alumina, such as boehmite, Al.sub.2 O.sub.3.H.sub.2 O; and (C) a clean thermal precursor of aluminium oxide; and, where y is not zero, with at least one of (D) chromium(III) oxide, Cr.sub.2 O.sub.3 ; (E) hydrous chromium (III) oxide; and (F) a clean thermal precursor of chromium (III) oxide, the relative amounts of the components of the mixture being adjusted to give the desired values of m and y when the mixture is heated. |

A preform for being embedded in a matrix material for making a composite material is made essentially of many short fibers stuck together by a quantity of dried binder. This preform has a first portion in which the fiber volume proportion is relatively high, a second portion in which the fiber volume proportion is relatively low, and a third portion, joining between the first portion and the second portion, in which the fiber volume proportion changes substantially continuously from its portion adjoining to the first portion to its portion adjoining to the second portion. Thereby, the characteristics of the composite material, such as its strength, heat and wear resistance, and machinability and workability and characteristics with respect to wear on a mating member, alter smoothly from the first portion to the second portion without any severe discontinuity, thus ensuring that no points of weakness are caused. A method for making such a preform, and a composit material object manufactured using such a preform, which may be an engine piston, are also disclosed. |

The invention provides a novel light-weight building material suitable for heat and sound insulation from an aluminum hydroxide sludge, which is a very noxious industrial waste material, and disintegrated scrapped paper as the base components. The sludge is first alkalized by the addition of sodium hydroxide to dissolve the gel-like aluminum hydroxide in the form of sodium aluminate and then admixed with the disintegrated scrapped paper to give a slurried mixture which is next neutralized to a weakly acidic condition by adding phosphoric acid whereby insoluble phosphates are deposited on the cellulosic fibers. The slurried mixture is further admixed with a coagulating agent to give a coagulated mass of the fibrous material with deposition of the phosphates. The coagulated mass is then separated from the liquid portion and dried to give a light-weight mass which is used as a blow-on insulating material for buildings or as a material for shaping an insulating board or slab. |

The invention provides a novel aluminum hydroxide-based spray-on insulating material which is workable by blowing to form a layer on the ceiling or wall of a building effective for heat and sound insulation. The inventive material is prepared by first blending an organic fibrous material, e.g. reclaimed pulp from scrapped papers, with a gel-like amorphous aluminum hydroxide sludge, available in large quantities as a waste in the anodization treatment of aluminum articles, with adjustment of the pH of the mixture to weakly acidic whereby the organic fibers are entrammeled by the coagulated aluminum hydroxide and then a powdery aluminum hydroxide, which is prepared by drying and pulverizing the gel-like aluminum hydroxide sludge, is admixed with the mixture followed by drying and disintegrating the blend into fluffs. The spray-on insulating material is worked by blowing as such or may be blown together with an adhesive so as to increase the mechanical stability of the insulating layer. |
