摘要： PROBLEM TO BE SOLVED: To provide an improved method for producing a zinc oxide powder without generating a cake-like material in an evaporation zone and an oxidation zone.
SOLUTION: In the evaporation zone, a gas flow of an inert gas and a fuel gas is passed through a melt of zinc having a temperature of 780-850°C while forming zinc vapor. In this case, the content of the fuel gas is 1-50 vol.% based on the total volume of the inert gas and the fuel gas, and the molar ratio of the zinc vapor to the fuel gas is 0.01-50. In the oxidation zone, a second gas flow containing an oxygen-containing gas and steam is added to a gas flow of the zinc vapor, the fuel gas, and the inert gas in such an amount that the temperature in the oxidation zone is kept within a range of 500-1,000°C.

摘要： Pyrogenically prepared zinc oxide powder having a BET surface area of from 10 to 200 m 2 /g, which is in the form of aggregates, the aggregates being composed of particles having different morphologies, and 0-10% of the aggregates being in a circular form, 30-50% being in an ellipsoidal form, 30-50% being in a linear form and 20-30% being in a branched form. It is prepared by reacting a starting mixture containing zinc vapour, a combustible gas and steam or a mixture of steam and carbon dioxide in a flame with an oxygen-containing gas in an oxidation zone, cooling the hot reaction mixture in a quenching zone and separating the solid material from the gas stream, the amount of oxygen in the oxidation zone being greater than the amount necessary for the complete oxidation of the combustible gas and the zinc vapour. The zinc oxide powder can be used as a constituent of sun protection compositions for protection against UV radiation.
