    Abstract: PROBLEM TO BE SOLVED: To obtain a powder increased in fluidity and bulk density without causing additional organic contamination of air by adding an alkylhalosilane to an aqueous suspension of a zeolite powder and drying the suspension. SOLUTION: At least one alkylhalosilane is added to an aqueous suspension of a zeolite powder, especially a filter cake obtained after precipitation and filtration of the zeolite and redispersed in water. The resultant suspension is then dried to afford a crystalline zeolite having the surface modified with the alkylhalosilane and containing the alkylhalosilane in an amount of 0.01-5 mass% based on the amount of the zeolite used. In order to use the zeolite as a detergent, a zeolite with a high Al content having sufficient calcium binding power and represented by the formula aMe2O.bAl2O3.cSiO2.dH2O [Me is Na, Na and/or K; (a)/b is 0.8-1.2; c/b is 1.8-5; d is 0-10] is preferably used.

    Abstract: Titanium-zirconium mixed oxide powder in the form of aggregated primary particles, which powder has a content of titanium dioxide of from 40 to 97 wt . % and a content of zirconium dioxide of from 3 to 60 wt.%, wherein the sum of the contents of titanium dioxide and zirconium dioxide is at least 99.7 wt.% and wherein the contents are in each case based on the total amount of powder, and which exhibits reflections of titanium dioxide modifications and does not exhibit reflections of monoclinic, tetragonal and cubic zirconium dioxide in X-ray diffraction analysis. It is prepared by transporting into a mixing chamber a starting compound, in vapour form, for the first mixed oxide component by means of primary air and a starting compound, in vapour form, for the second mixed oxide component by means of an inert gas, mixing the mixture with hydrogen in a mixing chamber and burning it into a reaction chamber. It can be used as a catalyst support.
