| 20080308010 | Economical Process of Manufacturing Very Fine Co-Ground Calcium Carbonate Material of the Gcc and Pcc Type, Obtained Products and Their Uses - An object of the present invention is to provide a process to obtain a calcium carbonate material comprising GCC and PCC, presenting a fraction of particles finer than 1 μm of greater than 80%, preferably of greater than 85%, more preferably of greater than 90%, and even more preferably of greater than 95%, and a specific surface area of less than 25 m | 12-18-2008 |
| 20090301351 | PROCESS TO DISPERSE AND/OR GRIND AND/OR CONCENTRATE CALCIUM CARBONATE IN AQUEOUS MEDIA USING AN AQUEOUS SOLUTION CONTAINING ZIRCONIUM COMPOUNDS - It is an object of the present invention to provide a process of manufacturing calcium carbonate-containing slurries, wherein said calcium carbonate-containing slurries are prepared by adding one or more zirconium compounds, and possibly one or more further phosphate-free additives acting as dispersing and/or grinding aid agents. An other object of the invention lies in calcium carbonate-containing slurries thus obtained, and dry calcium carbonate mineral pigments resulting from the drying of such slurries. A further object of the invention is the use of such slurries and such dry mineral pigments in paper manufacturing, plastic coatings, as fillers for plastics or for aqueous paint compositions and the like. Papers, paints and plastics containing such slurries and such dry pigments are also an object of the present invention. | 12-10-2009 |

An other object of the invention lies in calcium carbonate-containing slurries thus obtained, and dry calcium carbonate mineral pigments resulting from the drying of such slurries. A further object of the invention is the use of such slurries and such dry mineral pigments in paper manufacturing, plastic coatings, as fillers for plastics or for aqueous paint compositions and the like. Papers, paints and plastics containing such slurries and such dry pigments are also an object of the present invention. | 08-11-2011 |
| 20130333592 | DISPERSION OF ZIRCONIUM OXIDE AND PROCESS FOR PRODUCING THE SAME - The invention provides a process for producing an aqueous dispersion of zirconium oxide that includes: reacting a zirconium salt with an alkali in water to obtain a slurry of particles of zirconium oxide; filtering, washing, and repulping the slurry; adding an organic acid to the resulting slurry in an amount of one mole part or more per mole part of the zirconium in the slurry; hydrothermally treating the resulting mixture at a temperature of 170° C. or higher; and washing the resulting aqueous dispersion of particles of zirconium oxide. | 12-19-2013 |
| 20140041550 | PROCESS OF PREPARING MINERAL MATERIAL WITH PARTICULAR CERIA-CONTAINING ZIRCONIUM OXIDE GRINDING BEADS, OBTAINED PRODUCTS AND THEIR USES - An object of the present invention is to provide a process to grind at least one mineral material in the presence of ceria (CeO | 02-13-2014 |
| 106451000 | Vanadium or praseodymium containing (V, Pr) | 1 |
| 20090308283 | Zirconium Oxide Powder, Process For Producing The Same, And Material For Thermal Spraying - The present invention provides a zirconium oxide powder, a method for producing.the same, and a material for thermal spraying. The material for thermal spraying comprises a zirconium oxide powder comprising polyhedral particles each having not less than 6 faces, wherein the zirconium oxide powder has D50 of not less than 5 μm and less than 15 μm and a D90/D10 of less than 3. D10, D50 and D90 correspond to the point where the cumulative mass from the small-particle-diameter side reaches 10%, 50%, and 90% in the cumulative particle size distribution. | 12-17-2009 |
