| description | Production of particles coated with titanium dioxide comprises continuously feeding a mixture of finely divided titanium dioxide and jet particles through a flame of a reactor with the aid of conveying air; and sintering the titanium dioxide onto the surfaces of the particles at 600-1200 degrees C for 0.1-5 seconds. An Independent claim is also included for a process for increasing the adhesion between a metal structure and blended materials in dentures. Preferred Features: The mixture is blown into an annular flame operated using fuel gas using conveying air at a velocity of 1-50 m/s. The jet particles consist of ceramic, glass or metal as base material, preferably aluminum oxide. The particles have a diameter of 1-500, preferably 20-250 micro m. The titanium dioxide particles have a diameter of 0.001-10, preferably 0.01-0.1 micro m. The mixture contains (in wt.%) 0.1-30, preferably 1-5 titanium dioxide, and 70-99.9, preferably 95-99 jet particles. |
