| description | Titandioxidpreßlinge werden hergestellt, indem man pyrogen hergestelltes Titandioxid in Gegenwart von vollentsalztem Wasser mit einem Befeuchtungsmittel und/oder einer Base und/oder gegebenenfalls einem Bindemittel und/oder gegebenenfalls einem Verformungshilfsmittel und/oder gegebenenfalls einem Porenbildner intensiv vermischt, die erhaltene Masse bei Drücken zwischen 5 und 100 bar zu Formkörper extrudiert, die Formkörper bei Temperaturen zwischen 50 und 120 °C trocknet und anschliessend in Umgebungsluft bei Temperaturen von 400 bis 700 °C 1 bis 5 Stunden kalziniert.
Pressed titanium dioxide is produced by intensively mixing pyrogenically prepared titanium dioxide in the presence of deionised water with a humectant and/or a base and/or, if appropriate, a binder and/or, if appropriate, a forming aid and/or, if appropriate, a pore former, extruding the resulting mass at pressures of between 5 and 100 bar to give mouldings, drying the mouldings at temperatures between 50 and 120 DEG C and then calcining them for 1 to 5 hours in ambient air at temperatures from 400 to 700 DEG C. |
