Abstract
Official abstract text for this publication.
The present invention relates to a nanoparticulate composition comprising nanoparticles with a particle-size distribution of d 90 ≦10 μm, and optionally a surface-active agent. The present invention further relates to a method for the production of such a nanoparticulate composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A nanoparticulate composition in the form of a dried, finely particulate powder, comprising non-agglomerated nanoparticles of a transition metal compound with a particle-size distribution d 90 ≦10 μm and d 50 of 0.4 to 0.7 μm, wherein the nanoparticles are composed of a material comprising FePO 4 .2H 2 O, Fe 2 (PO 4 ) 2 , or mixtures thereof; and wherein the composition further comprises a surface-active agent in a quantity of 0.01 to 1 wt. % relative to the total weight of the composition. 2. Composition according to claim 1 , wherein the nanoparticles are present in crystalline state. 3. Composition according to claim 1 , wherein the nanoparticles have a carbon-containing coating. 4. Composition according to claim 1 , wherein the composition is sulphate-free. 5. Composition according to claim 1 , wherein the surface-active agent has an ionic character.
