20130089706 | Infrared-Reflective Coatings - A composition includes polymer and dispersed infrared-reflective clusters of titanium dioxide primary particles. The titanium dioxide primary particles are cemented together with precipitated silica and/or alumina to form clusters. The titanium dioxide primary particles have an average particle diameter in the range of from about 0.15 to about 0.35 micron, while the clusters of titanium dioxide primary particles have an average cluster diameter in the range of from about 0.38 to about 5 microns and a geometric standard deviation (GSD) in the range of from about 1.55 to about 2.5. | 04-11-2013 |
20130040130 | Pigment For Paper And Paper Laminate - A pigment mixture comprising (a) pigment particles, (b) colloidal spacer particles dispersed on surfaces of the pigment particles, and (c) carrier particles, wherein the pigment particles with colloidal spacer particles are dispersed on surfaces of the carrier particles. A pigment mixture of titanium dioxide pigment particles having colloidal silica spacer particles on surfaces of the titanium dioxide, the titanium dioxide and colloidal silica attached to surfaces of diatomaceous earth carrier particles, provides improved optical efficiency of the pigment and improved retention in a paper fiber matrix. | 02-14-2013 |
20120201732 | CE CONTAINING, V-FREE MOBILE DENOX CATALYST - A catalyst for removal of NOx from exhaust gas, containing cerium oxide and titanium dioxide, wherein a first portion of the cerium oxide forms at least one agglomerate of cerium oxide crystallites interdispersed in the titanium dioxide, and a second portion of the cerium oxide forms at least one island on a surface of the titanium dioxide, a method for producing the catalyst, a process for selectively reducing NOx levels in an exhaust gas using the catalyst, and an SCR canister containing the catalyst therein. | 08-09-2012 |
20090062111 | Transparent, Stable Titanium Dioxide Sols - A method of preparing stable, transparent photocatalytic titanium dioxide sots is disclosed which involves thermal treatment of a suspension of amorphous titanium dioxide in the presence of certain alpha-hydroxy acids. The sots comprise titanium dioxide particles in the anatase form having a crystallite size less than about 10 nm and exhibit excellent stability and transparency at basic, neutral, and acid pH. | 03-05-2009 |
20090061246 | Photocatalytic Coating - De-polluting, self-cleaning coating compositions are disclosed which comprise an organic binder having dispersed therein photocatalytic titanium dioxide particles substantially in anatase form which have an average crystallite size between about 1 nm and about 150 nm and which preferably have photocatalytic activity in the presence of visible light. Advantageously, the coatings of the invention do not require pre-activation to achieve high initial photocatalytic activity against pollutants in the air, such as NO | 03-05-2009 |
