    Abstract: PROBLEM TO BE SOLVED: To provide a cerium oxide powder, a method for producing the same, and a dispersion liquid containing the powder.
    SOLUTION: The cerium oxide powder has a BET surface area of 25-150 m
    2 /g and contains primary particles having an average diameter of 5-50 nm. The layer close to the surface of each primary particle has a depth of about 5 nm, and the carbonate concentration in the layer close to the surface is decreased toward inside from the surface. The content of carbon deriving from carbonate groups is 5-50% by area percentage on the surface and 0-30% by area percentage at a depth of about 5 nm in the layer close to the surface. The content of cerium oxide is at least 99.5 mass% based on powder. Further, the content of carbon is 0.01-0.3 mass% based on powder. The dispersion liquid is sufficiently stable even when an additive is not added additionally and can be used for chemical and mechanical polishing within a range from neutrality to weak alkalinity.

    Abstract: 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.

    Abstract: PROBLEM TO BE SOLVED: To manufacture an aerosol which contains a highly concentrated salt solution in a gas phase and at the same time, ensures a liquid droplet spectrum having as small a liquid droplet diameter as possible. SOLUTION: This aerosol of small liquid droplet is manufactured by a device of such a functional structure that ultrasonic vibrators vibrate level with a liquid level or an a 1-20 deg. inclined plane, then each of the vibrators placed in a recessed part unexceptionally vibrates level with the liquid level or on the 1-20 deg. inclined plane, and a liquid of such a nature that its height can be controlled on a vibrating plane is present on the ultrasonic vibrators. Thus it is possible to obtain the aerosol which shows a liquid load exceeding 100 g/Nm in the gas phase and the d90 value of a liquid droplet spectrum at not more than 30 μm.
