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.
