Granulate von Metallen und Metalloxiden

DE 102006055975 A1 UPAB: 20080815 NOVELTY - Oxidic or non-oxide metal compounds granulate production involves spray drying of a dispersion, which contains water, particles of oxidic or non-oxide metal compounds and a dispersion agent. The portion of oxidic or non-oxide metal compounds is 40-70 wt.% and the sum of the portion of water and the particles is 70 wt.%. The particles have Brunauer, Emmett, and Teller (BET) surface of 20-150 m2/g and have a median of the particle size smaller than 100 nm. The dispersion agent is present with a portion of 0.25-1 wt.% relating to the oxidic or non-oxide metal compounds. USE - Method for producing granulate of oxidic or non-oxide metal compounds for producing ceramic molded articles, particularly by dry pressing. ADVANTAGE - The oxidic or non-oxide metal compounds granulate producing method ensures availability of dispersion in a form, which is suitable for the production of molded articles
