| 20120110921 | GESINTERTE SCHLEIFKORNAGGLOMERATE SINTERED ABRASIVE GRIT AGGLOMERATES - The present invention relates to sintered abrasive grit agglomerates based on aluminum oxide, having homogeneously distributed nanoscale pores in the range of 100-300 nm, with a pore volume of at least 15%. The average diameter of primary particles of the aluminum oxide primary particles is less than 5 μm, wherein said primary particles are connected to each other without additional adhesive agent. | 05-10-2012 |
| 20110300372 | WEAR PROTECTION COATING BASED ON A SYNTHETIC RESIN MATRIX, METHOD FOR THE PRODUCTION THEREOF AND USE THEREOF - The invention relates to a wear protection layer comprising a mixture of non-uniform transparent hard material particles, which are stored in a matrix material and which comprise a Mohs hardness of at least 6 and transparent solid material particles, wherein the transparent solid material particles encompass a bi-modal grain size distribution. The invention also relates to a method for producing a wear protection layer as well as the use thereof for producing wear protection surfaces, in particular surfaces on wood fiber boards, which are provided with a décor. | 12-08-2011 |
| 20090162656 | Spherical Corundum Particles, Based on Fused Aluminum Oxide and a Method for Said Particles - A method is provided for manufacturing spherical corundum grains having a bulk density between 1.5 kg/L and 2.5 kg/L, with aluminum oxide being melted in an electric arc furnace with the addition of 0.1 to 1% quartz sand, the melt being poured in a pouring quantity of less than 100 kg/min, and the pouring stream being blown using compressed air at a pressure between 3 to 10 bar. | 06-25-2009 |
