摘要： 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.

摘要： A method for producing a precipitated silicon dioxide having a new combination of physical and chemical properties is disclosed. The pigments are produced by acidulating a solution of an alkali metal silicate with an acid under controlled precipitation conditions. The aqueous reaction medium comprising the precipitated silica is then post-conditioned by introducing a second silicate solution into the reaction vessel and thereafter adding additional acid to react with the said second silicate solution. By varying the amount of the silicate employed in the post-conditioning step, a product is obtained which has a unique combination of physical and chemical properties including reduced wet cake moisture content, high surface areas and oil absorptions, improved surface activity, friability, wetting characteristics, and the like. The product has particular utility for use as a rubber reinforcing agent because of its increased surface activity and oil absorption, etc. The product, however, may be used in paints, paper, detergents, dentifrice compositions, molecular sieves, and polymeric compositions. An unexpected discovery of the invention involves the production of a rubber reinforcing silica which has a decreased wet cake moisture content. In one particularly advantageous embodiment, an adduct material, such as aluminum, is added to control the refractive index and surface area of the product.

摘要： The corrosion and staining of unlined aluminum tube surfaces by dentifrices such as toothpastes, particularly when the dentifrices contain therapeutic agents, is substantially prevented by incorporation into the dentifrice of a controlled amount of an alkaline earth metal ion such as calcium ion, in the range of 0.005-0.2 weight percent, and preferably in the range of 0.005-0.070 weight percent of the dentifrice. The alkaline earth metal may be provided from any water soluble alkaline earth metal salt or as a reaction product of the alkaline earth metal salt with an amorphous silica abrasive and/or thickener.

摘要： A process for producing precipitated silicic acid products having new and improved properties is disclosed. The silica products are produced by the simultaneous introduction of a solution of an alkali metal silicate and an acid, such as sulfuric acid, into an aqueous receiving medium which contains a salt or electrolyte. The pH of the aqueous receiving medium is adjusted prior to the introduction of the acid and silicate so that it is the same or equal to that pH at which the precipitation of the pigment is effected. The electrolyte is preferably a metal salt of the acid used for acidulation of the silicate. The acid and silicate are added to the receiving medium at a rate such that the precipitating pH is maintained constant. The products of the invention are characterized by their high abrasiveness and have a relative cleaning ability or scale (RCS) equivalent to high grade phosphates used as polishing agents in toothpastes and a superior fluoride compatibility to that of said phosphates. The silicates used in the process are preferably those which are partially polymerized and have a SiO.sub.2 /Na.sub.2 O ratio of at least 2.0.

In particular, precipitated silica compositions of the present invention have a 40% slurry viscosity build of less than approximately 20,000 centipoise and a 10% Brass Einlehner abrasion value of approximately 2.5 to 20.0 mg loss/100,000 rev.
