| 20080249237 | Process for Producing Ultrafine Powders Based on Polyamides, Ultrafine Polyamide Powders and Their Use - Process for preparing ultrafine powders based on polyamides by contacting polyamides having a relative solution viscosity η | 10-09-2008 |
| 20080312067 | Highly Filled Dispersion Containing Transition Aluminium Oxide - Aqueous dispersion containing transition aluminium oxide as only solid and a dispersant, in which—the transition aluminium oxide is present in the form of aggregates of primary particles, the content of transition aluminium oxide in the dispersion is from 40 to 65% by weight, the aggregates in the dispersion have a mean aggregate diameter of less than 100 nm,—the dispersant contains polyaluminium hydroxychloride, polyaluminium hydroxynitrate and/or polyaluminium hydroxysulphate, the dispersion has a pH of from 3 to 5. | 12-18-2008 |
| 20090105354 | DISPERSION OF ZIRCONIUM DIOXIDE AND ZIRCONIUM MIXED OXIDE - Dispersion of zirconium dioxide having a solids content of from 30 to 75 wt. %, based on the total amount of the dispersion, and a median value of the particle size distribution in the dispersion of less than 200 nm, obtainable by predispersing a zirconium dioxide powder and/or a zirconium mixed oxide powder having a ZrC>2 content of at least 70 wt. %, the powders being in the form of aggregated primary particles and having no internal surface and a BET surface area of the powder of 60±15 m2/g, in a dispersing agent in the presence of from 0.1 to 5 wt. %, based on the total amount of the dispersion, of a surface-modifying agent with an energy input of less than 200 KJ/m3, dividing the predispersion obtained into at least two part streams, placing these part streams under a pressure of at least 500 bar in a high-energy mill and decompress them via a nozzle, these part streams colliding with one another in a gas- or liquid-filled reaction chamber and thereby being ground, and optionally subsequently adjusting the dispersion to the desired content with further dispersing agent. It can be used for the production of ceramic layers, membranes and shaped articles. | 04-23-2009 |
| 20090272296 | Process for the Preparation of Products of High Early Strength Comprising Hydraulic Binders - A process for the preparation of products of high early strength comprising hydraulic binders, in which a hydraulic binder, water and 0.1 to 5% by weight, based on the hydraulic binder, of a finely divided titanium dioxide are mixed with agitation and in any desired sequence. | 11-05-2009 |
