| 20120115711 | PHOTOCATALYST COMPRISING TiO2 AND ACTIVATED CARBON MADE FROM DATE PITS - A photocatalyst is provided that comprises activated carbon produced from date pits, impregnated with TiO | 05-10-2012 |
| 20120114542 | PHOTOCATALYST COMPRISING TiO2 AND ACTIVATED CARBON MADE FROM DATE PITS - A photocatalyst is provided that comprises activated carbon produced from date pits, impregnated with TiO | 05-10-2012 |
| 20120111234 | CHLORIDE INGRESS-RESISTANT CONCRETE - An reinforced cementitious material structure is provided that includes a cementitious material made from an industrial waste byproduct from a titanium metal production process or from a titanium dioxide production process. The byproduct is used as a partial cement replacement. In some embodiments, the reinforced cementitious material structure can comprise a metal reinforcing structure in contact with a hardened cementitious material. The hardened cementitious material can comprise cement and the industrial waste byproduct. The cement can be used to make concrete and other cementitious material products for structural and non-structural uses, with little or no corrosion or other deterioration of an embedded metal reinforcing structure. | 05-10-2012 |
| 20120007023 | Sodium Silicate Solutions - A method is provided for treating silica sand scrubs (SSS) generated and accumulated as waste in the chloride manufacturing process of titanium dioxide pigment. A hydrothermal process is used to produce sodium silicate solutions of modulus 3.0 to 3.8, and precipitated silicas. In some embodiments, the process uses two specific principal reaction stages. A sodium silicate solution having a low SiO | 01-12-2012 |

| 20110135919 | CHLORIDE INGRESS-RESISTANT CONCRETE - An reinforced cementitious material structure is provided that includes a cementitious material made from an industrial waste byproduct from a titanium metal production process or from a titanium dioxide production process. The byproduct is used as a partial cement replacement. In some embodiments, the reinforced cementitious material structure can comprise a metal reinforcing structure in contact with a hardened cementitious material. The hardened cementitious material can comprise cement and the industrial waste byproduct. The cement can be used to make concrete and other cementitious material products for structural and non-structural uses, with little or no corrosion or other deterioration of an embedded metal reinforcing structure. | 06-09-2011 |
| 20110059315 | Methods of producing titanium dioxide nanoparticles - A method is provided for producing TiO | 03-10-2011 |
| 20100206198 | TITANIUM PRODUCTION WASTE BYPRODUCT AS PARTIAL CEMENT REPLACEMENT - An industrial waste byproduct from a titanium metal or a titanium dioxide production process can be utilized as a partial cement replacement. In some embodiments, the byproduct can comprise a byproduct from the production of titanium dioxide pigment from a sulphate process or from a chloride process. The cement can be used to make concrete and other cementitious material products for structural and non-structural uses, for example, grout, mortar, gunite, stucco, masonry, decorative stonework, bricks, blocks, roof tiles, floor tiles, cobblestones, pavers, combinations thereof, and the like. | 08-19-2010 |
| 20090087556 | Method for surface treatment of titanium dioxide pigment - A method of preparing coated titanium dioxide particles is provided wherein a zirconium oxide coating and an aluminum oxide coating are formed on the surface of titanium dioxide particles. The zirconium oxide-forming and aluminum oxide-forming coating materials can be used to control the pH of the surface treatment process without the need for adding pH controlling agents. | 04-02-2009 |
