    • Pyrogenically, especially flame-hydrolytically produced zirconium dioxide powder with a specific surface area between 20 and 200 m2/g, a primary particle size between 7 and 100 nm, a tamped density of the deacidified and non-deacidified zirconium dioxide between 40 and 150 g/l with Sears numbers of the deacidified and non-deacidified zirconium dioxide between 1 and 20 ml/2 g and with a chlorine content of the deacidified zirconium dioxide less than 0.6% by weight. These are produced by evaporating zirconium halides, mixing the vapors alone or together with a carrier gas in a burner with air, oxygen, nitrogen and hydrogen, causing the gases to react with each other in a flame in a closed burner chamber, cooling off the waste gases and the zirconium dioxide in a heat exchanger unit, separating the waste gases from the zirconium dioxide and removing any halide remnants adhering to the zirconium dioxide by a heat treatment with moistened air.
    • 热原性地,特别是火焰水解生产的二氧化锆粉末,比表面积为20至200m2 / g,一次粒径在7至100nm之间,脱酸和非脱酸二氧化锆的密度为40-150g / S,数量为1至20ml / 2g之间的脱酸和非脱酸二氧化锆,并且脱酸二氧化锆的氯含量小于0.6重量%。 这些是通过蒸发卤化锆,将蒸气单独或与气体一起携带在具有空气,氧气,氮气和氢气的燃烧器中的气体混合而产生的,导致气体在封闭的燃烧器室中的火焰中彼此反应,冷却 废气和二氧化锆在热交换器单元中分离废气和二氧化锆,并通过用湿润的空气进行热处理除去附着在二氧化锆上的任何卤化物残余物。
