Abstract: A friction lining comprising an inorganic silicate-containing binder without resin binder components, comprising a mixture of finely divided SiO.sub.2 (constituent a) and at least partially water-soluble silicates (constituent b). The mixture of constituent a and constituent b are cured in the presence of water at low temperatures, thereby forming a three-dimensional inorganic polysilicate matrix. Heterogeneous additive particles are incorporated into the three-dimensional inorganic polysilicate matrix during curing of the mixture at low temperatures, thereby forming a solid body with the additive particles serving as fillers, sliding agents, lubricants or coefficient of friction modifiers. These additive particles do not include resin binder forming agents.

Abstract: A reagent material useful for converting a contaminated waste material, which is environmentally unacceptable, to a relatively harmless granular substance which is environmentally acceptable. The reagent material is comprised of an effective amount of alumina, silica, a hydroxide, or hydroxide precursor, of an alkali metal, calcium oxide, and a medium to large pore zeolitic material. The method involves blending an effective amount of the reagent material with the waste material and allowing it to dry without setting, thereby resulting in an environmentally acceptable particulate substance.

Abstract: A high temperature resistant seal for a catalytic converter is made from a high temperature resistant material including between approximately 28 and 60 dry weight percent high temperature resistant ceramic fibers and between approximately 20 and 50 dry weight percent high aspect ratio vermiculite. The seal is formed by mixing the resistant ceramic fibers with an aqueous dispersion of high aspect ratio vermiculite, applying the resultant mixture to a monolithic catalyst structure of a catalytic converter and heating the mixture and the monolithic catalyst structure to evaporate the water from the mixture. The seal and the monolithic catalyst structure can then be assembled in a housing to form a catalytic converter.

Abstract: A family of novel and unique synthetic alkali metal alumino-silicates (SAMS) are produced by the hydrothermal reaction between kaolin and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 :zH.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is the alkali metal, y is the number of moles of SiO.sub.2 in the unique SAMS compositions and is an integer greater than 2.0, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO.sub.2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.

Abstract: A monolith can be mounted in a catalytic converter by a material containing intumescent vermiculite flakes that have a uniform content of chemically bound water from about 1.0 to 3.2% by weight and a uniform bulk density from about 0.2 to 0.9 g/cm.sup.3. Such a mounting affords good support to the monolith at warm-up temperatures, exerts adequate holding forces at operating temperatures without danger of cracking the monolith, and does not incur gradual reduction in holding forces at operating temperatures.
