摘要：
Titanium dioxide compacts are produced by intensively mixing pyrogenically produced titanium dioxide in the presence of deionized water with a wetting agent and/or with a base and/or optionally with a binder and/or optionally with an auxiliary deformation agent and/or optionally with a pore former, extruding the mass thus obtained at pressures between 5 and 100 bars to form shaped articles, drying the shaped articles at temperatures between 50.degree. and 120.degree. C. and subsequently calcining the shaped articles in the ambient air at temperatures of 400.degree. to 700.degree. C. for 1 to 5 hours.
