摘要:
A process for preparing grit blasting particles coated with titanium dioxide by sinter-fusing titanium dioxide on the surface of grit blasting particles made of a base material. A mixture of finely divided titanium dioxide and grit blasting particles is passed continuously through the flame in a flame reactor, with the aid of conveying air, wherein the titanium dioxide is sinter-fused on the surface of the grit blasting particles over an average residence time of 0.1 to 5 seconds in a temperature range from 600 to 1200° C. An increase in the adhesive bond between metal framework and a facing material made of plastics in dentures can be achieved when metal framework is grit blasted with a grit blasting agent containing titanium dioxide coated grit blasting particles and then the grit blasted and titanium dioxide coated surface is treated with a silane bonding agent.

Pyrogenically prepared, doped zinc oxide powder, wherein the doping component comprises at least one oxide from the group aluminum, gallium, indium, germanium, tin and is present in the doped zinc oxide powder in an amount of from 0.005 to 15 wt. %, and wherein the doped zinc oxide powder is in the form of aggregates of primary particles having a mean maximum diameter of from 30 to 400 nm. It is prepared by oxidation from zinc powder and at least one doping agent, wherein the process zones vaporisation, nucleation, oxidation and quenching are passed through and the doping agent is metered in in the nucleation zone, in which the temperature is below the boiling temperature of zinc. The doped zinc oxide powder can be used in electrically conductive lacquers and coatings.

摘要:
To supply energy to motorised vehicles, a heat engine (SM) is provided to convert heat (106, 107, 108, 114) that accumulates in the vehicle at least partly into kinetic energy of the vehicle and to feed other portions of said lost heat to a heat accumulator (LWS). An optional, mechanical energy accumulator (MES) can take up kinetic energy from a vehicle motor (MGH), store said energy and deliver said energy back to a vehicle motor (MGM when required.
