    • 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.
    • 钛 - 锆混合氧化物粉末为聚集的一次颗粒形式,该粉末的二氧化钛含量为40-97wt。 %和二氧化锆的含量为3至60重量%,其中二氧化钛和二氧化锆的含量之和为至少99.7重量%,其中每种情况下的含量基于粉末的总量 并且其表现出二氧化钛修饰的反射,并且在X射线衍射分析中不显示单斜晶,四方晶和立方二氧化锆的反射。 通过惰性气体将第一混合氧化物组分的蒸气形式的第一混合氧化物组分的蒸气形式的原料化合物输送到混合室中, 将混合物与氢气混合在混合室中并将其燃烧成反应室。 它可以用作催化剂载体。
