20140141967 | CERIA ZIRCONIA ALUMINA COMPOSITION WITH ENHANCED THERMAL STABILITY - A process for the preparation of a composition comprising Al-, Ce- and Zr-oxides, which process comprises the steps of (a) preparing an aqueous solution of a mixture of metal salts of cerium, zirconium and aluminium, which aqueous solution optionally comprises one or more salts of the Rare Earth Metals other than cerium, (b) adding to the solution obtained a base at temperatures from 0° C. to 95° C. and precipitating the mixed metal salts in the form of hydroxides or oxy-hydroxides, (d) treating the aqueous suspension obtained in step (b) with a surfactant, and (e) isolating the precipitate obtained in step (d) and treating said precipitate at a temperature from 450° C. to 1200° C., which process is characterized in that the alumina content is in the range from 35 to 80% by weight, and the surface area (BET) of the composition obtained, measured according to DIN (Deutsche Industrie Norm) 66131 after calcining for 2 hours at 1100° C. is from 55 to 80 m | 05-22-2014 |
20120264587 | ZIRCONIA CERIA COMPOSITIONS - Composition in the form of a solid-solid solution which is phase stable at 1150° C./36 hours and at 1200°/4 hours and which exhibits a thermal stability in surface area of at least 15 m | 10-18-2012 |
20110150731 | CATALYST COMPOSITION FOR SELECTIVE CATALYTIC REDUCTION OF EXHAUST GASES - A catalyst composition represented by the general formula XVO | 06-23-2011 |
20100043999 | YTTRIA-BASED REFRACTORY COMPOSITION - Method for producing a mold for use in casting reactive metals comprising preparing a slurry of a yttria-based refractory composition and a binder, and using said slurry as a mold facecoat by applying said slurry onto a surface of a mold pattern, wherein said yttria-based refractory composition is obtainable by (a) mixing particles of a yttria-based ceramic material and a fluorine containing dopant, and (b) heating the resulting mixture to effect fluorine-doping of said yttria-based ceramic material. | 02-25-2010 |
20090035579 | Solid particles, method and device for the production thereof - The invention relates to solid particles and to a method for the production thereof from a flowable starting material and a solid part, wherein the flowable starting material is split into droplets which are introduced along a trajectory into a solidification liquid in which they are solidified in the form of the solid particles. The invention is characterized by the use of solidification liquid and, if the flowable starting material contains actinide oxide, the solidification liquid steadily flows, thereby making it possible to produce solid particles having a greater sphericity and a narrow particle sized distribution. | 02-05-2009 |
20080307712 | Ceria Based Glass Polishing Composition and a Process For the Manufacture Thereof - The invention is directed to a process for the manufacture of a ceria based polishing composition, comprising (a) suspending an inorganic cerium salt or cerium hydroxide with a cerium content calculated as cerium oxide in the range of 50%-100% based on Total rare earth oxide (TREO) in an aqueous medium thereby obtaining an aqueous suspension, (b) treating said aqueous suspension with an acid or a salt of an acid selected from the group of HF, H | 12-18-2008 |
20080216924 | METHOD FOR PRODUCING GRAIN REFINED MAGNESIUM AND MAGNESIUM-ALLOYS - The present invention relates to a method for producing grain refined Mg and Mg alloys by solidifying molten Mg or Mg-alloys in the presence of ZrB | 09-11-2008 |
