Abstract:
The invention relates to a transparent, UV-absorbent synthetic glass containing ZnO nanoparticles, to a method for the production thereof, to a nanoscale ZnO powder, and to a method for the production thereof. The ZnO powder is suitable for distribution in liquid polymer precursors. The crystals hardly differ, or only differ slightly, from pure synthetic glass, in terms of the transparence thereof.
Abstract:
Mixed oxide powder containing indium and tin, with a proportion of indium oxide of between 90 and 98 wt.% and a BET surface area of 40 to 120 m²/g, which is in the form of aggregates having an average circumference of less than 500 nm, consists of at least 95% of an indium oxide phase and displays an oxygen content that is lower than the content that theoretically results from In2O3 and SnO2. It is produced by mixing a solution of an indium compound with a solution of a tin compound, atomising this mixture of solutions, pyrolysing the atomised mixture of solutions in a first zone of a reactor and in a second zone of the reactor, following pyrolysis, adding reducing gases to the pyrolysed mixture at one or more points in a quantity such that overall a reducing atmosphere is established in this second zone, and separating the resulting solid from the waste gases in a further, third zone, in which a reducing atmosphere likewise still prevails. It can be used for the production of transparent, electroconductive paints and coatings.
Abstract:
HIGHLY-TRANSPARENT LASER-MARKABLE AND LASER-WELDABLE PLASTIC MATERIALS The present invention relates to high-transparency plastic materials which are laser-markable and/or laser-weldable due to a content of nanoscale laser sensitive metal oxides. These plastic materials, which may be provided as molded bodies, semifinished products, molding compounds, or lacquers, particularly contain metal oxides having particle sizes from 5 to 100 nm and a content of 0.0001 to 0.1 weight-percent. Typical metal oxides are nanoscale indium-tin oxide or antimony-tin oxide. These materials may be used in particular for producing laser-markable production products. No suitable figure

Abstract:
Paint binders (I) comprising a polymer-based matrix and a stabilised suspension of nano-particles in amounts of 0.5-25 wt.% particles based on 100 wt.% (I), in which the suspension is obtained by (a) milling the agglomerated and/or aggregated particles with a solvent in a high-energy mill at pressures from above 500 to about 10000 bar to form nano-scale fragments and (b) adding 1-25 parts by weight (pts. wt.) dispersant(s) to 100 pts. wt. particles to stabilise the particle surface. Independent claims are included for (1) a method for the production of (I) by making a polymer-based matrix and mixing it with a suspension (II) obtained as above, and optionally with other conventional additives (2) paint containing (I) (3) painted objects with a coating of hardened (I) .
