DE 102005061965 A1 UPAB: 20071008 NOVELTY - Oxidic agglomerate particles with an average particle diameter of 0.5-50 microns comprises an agglomerated oxidic nano-scale primary particles with an average particle size of 2-500 nm. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a process of incorporating agglomerate particles into a polymer matrix, comprising agglomeration of the oxidic nano-scale primary particles, in solid form, into a polymer matrix. USE - The agglomerate particles are useful for the production of: nano-dispersions, nano-composites and/or nano-coatings; lacquers, colors, inks, coating systems, flame protection systems and/or electrical rheologic fluids; and as composites for dielectric, electro optical, optical and electrical applications and medical application. The agglomerate particles are useful as cosmetic auxiliary material (claimed). ADVANTAGE - The agglomerate particles are hollow or compact. The agglomerate particles exist in a pourable non-dust form (all claimed). The agglomerate particles are safe to handle in industrial level. The agglomerate particle exhibits minimized surface energy and good wettability. The nanocomposite obtained using the agglomerate particle exhibits scratching firmness with essentially unchanged transparency and impact strength, hardness, frictional behavior, stiffness, thermal characteristics such as linear extension, heat conductivity, stability against environmental influences such as light and temperature change, gas and steam permeability, and optical characteristics such as gloss.
