Patent number: 6653255Abstract: This invention relates to highly purified biogenic silica product obtained from diatomite and methods for preparing same. More particularly, this invention pertains to highly purified non-calcined, calcined, and flux-calcined diatomite products which bear the distinguishing porous and intricate structure of silica unique to diatomite and which have an extraordinarily high silica (i.e., silicon dioxide, SiO2) content and low density, resulting in high silica specific volume. These products often also exhibit exceptionally low soluble metals content and/or extreme brightness.Type: GrantFiled: May 2, 2001Date of Patent: November 25, 2003Assignee: Advanced Minerals CoroporationInventors: Jerome C. Shiuh, Scott K. Palm, Timothy R. Smith, George A. Nyamekye, Jeffrey D. Taniguchi, Qun Wang

Patent number: 6524489Abstract: This invention relates to advanced composite filtration media comprising a functional filtration component and a matrix component, and methods for preparing and using same. More particularly, this invention pertains to advanced composite filtration media and advanced composite filtration media products comprised of a functional filtration component, such as a biogenic silica product (e.g., diatomite), a natural glass product (e.g., expanded perlite), or a natural or synthetic crystalline mineral (e.g., titanium dioxide), which is thermally sintered to a matrix component, such as an engineering polymer (e.g., glasses, natural or synthetic crystalline minerals, thermoplastics, and metals) or a suitable natural material (e.g., rice hull ash, sponge spicules) that has a softening temperature below that of the functional filtration component. This invention also relates to advanced composite media and advanced composite media products, generally, which are also useful in non-filtration applications.Type: GrantFiled: July 6, 1998Date of Patent: February 25, 2003Assignee: Advanced Minerals CorporationInventors: Scott K. Palm, Timothy R. Smith, Jerome C. Shiuh, John S. Roulston

Patent number: 5776353Abstract: This invention relates to advanced composite filtration media comprising (i) a functional filtration component and (ii) a matrix component, wherein said matrix component has a softening point temperature less than the softening point temperature of said functional filtration component, and wherein said functional filtration component is intimately bound to said matrix component; and methods for preparing and using same. More particularly, this invention pertains to advanced composite filter media and advanced composite filter media products comprised of a functional filtration component, such as a biogenic silica product (e.g., diatomite) or a natural glass product (e.g., expanded perlite) which bears a distinguishing porous and intricate structure suitable for filtration, which is thermally sintered to a matrix component, such as an engineering polymer (e.g., glasses, crystalline minerals, thermoplastics, and metals) that has a softening temperature below that of the functional filtration component.Type: GrantFiled: February 16, 1996Date of Patent: July 7, 1998Assignee: Advanced Minerals CorporationInventors: Scott K.

Patent number: 4557883Abstract: A process is described for the preparation of perlite ore fines for expansion. The ore fines are treated with an agglomerating agent which has a viscous liquid phase at a temperature above ambient temperature but below the critical dehydration temperature of the perlite ore fines. Suitable agglomerating agents mentioned are the boron acids, particularly orthoboric acid and metaboric acid. The perlite ore fines and agglomerating agent are mixed, preferably by dry mixing, and then heated to the temperature of the viscous liquid phase and held at that temperature for a short period while the liquid coats at least a portion of the perlite ore fines and effects agglomeration. Thereafter, the agglomerated perlite ore fines can be expanded in a conventional perlite ore expander. The resulting expanded materials have properties essentially identical to standard expanded perlite ore and are useful for such purposes as insulating fillers and light weight aggregates.Type: GrantFiled: February 5, 1982Date of Patent: December 10, 1985Assignee: Manville Service CorporationInventors: Jerome C.
