摘要： There is prepared an aqueous suspension which in addition to water, consists of 2 to 50 weight % of a mixture of bentonite and inorganic fibers, with the portion of inorganic fiber being 1 to 30 weight % and the portion of bentonite being 1 to 30 weight % and wherein the total amount of solids does not exceed 50 weight %. With the suspension there is attained an improvement of the mechanical properties of thermal insulating molded objects which are employed for thermal insulation and which for example, contain pyrogenically produced silica as a filler by delivery of this suspension on the thermal insulating plate. The suspension can also be delivered on thermal insulating molded bodies on which there is pressed a fiber net or a fiber felt. After applying the suspension several thermal insulating molded bodies can be joined together where the coating formed consisting of bentonite and inorganic fibers acts as binder. The heat insulating molded article in addition to this layer, can have one or more additional coatings based on organic or inorganic lacquer systems, silicone compositions or low melting glazes.

It is synthesized by a process wherein zirconium salt is added in calculated quantity to an aqueous aluminum sulfate solution, the resulting mixture is fed simultaneously with a sodium aluminate liquor into a water pool having a temperature of 50.degree. to 100.degree. C., thereby precipitating zirconium-doped alumina gel while a pH of 3.5 to 8 is maintained, the pH of the suspension is adjusted after addition of the aluminum sulfate solution to 8.5 to 10.5 by further addition of sodium aluminate liquor, the suspension is digested if necessary at the pH of 8.5 to 10.5 and the temperature of 50.degree. to 100.degree. C. for a period of up to 24 hours, the formed pseudoboehmite crystals are filtered off, the filter cake is redispersed with water and the suspension is sprayed-dried. By calcining at 700.degree. to 1100.degree. C., preferably at 850.degree. to 950.degree. C., the pseudoboehmite is further processed to zirconium-doped gamma-alumina suitable for automobile exhaust catalysts.
