METHOD FOR PRODUCING SILICA-COATED CARBON PRODUCT

PROBLEM TO BE SOLVED: To provide a method for producing a silica-coated carbon product. SOLUTION: In one method, an aqueous medium or solution and a carbon product are brought into contact with a solution comprising a silicate substantially free of metal ions, for a sufficient time and temperature to form the silica-coated carbon product. A method of producing the silica-coated product by bringing the aqueous medium and the carbon product into contact with a solution comprising monosilicic acid is also described as well as exchanging metal ions in a solution comprising a metallic silicate for hydrogen ions and bringing the aqueous medium and the carbon product into contact with the solution to form the silica-coated carbon product. The silica-coated carbon products resulting from these methods are also described and include a plurality of silica-coated products wherein each of the silica-coated product is substantially and uniformly coated with silica and in the substantial absence of free silica. Further, elastomeric composition and the like containing the silica-coated carbon product are described. COPYRIGHT: (C)2009,JPO&INPIT
