A composition is provided which contains an organic zinc compound represented by general formula R—Zn—R, in which Rrepresents a linear or branched alkyl group having 1 to 7 carbon atoms, and an organic metal compound containing a metal element whose oxide has a band gap smaller than 3.2 eV. The composition can be used to form a zinc oxide film by a droplet coating method, such as a spray coating method, at a base material temperature of less than 200° C. A method for producing a zinc oxide film involves coating the composition in the form of droplets at a base material temperature of less than 200° C. to form the zinc oxide film. Using this method, it is possible to provide a zinc oxide thin film having an ultraviolet ray absorption ability, excellent visible light permeability, and a thickness of 1 μm or less.

A method for producing a particulate aluminum alloy involves pulverizing an aluminum alloy in a hydrocarbon solvent in the presence of an organic aluminum compound. Methods for producing trialkylaluminum involve reacting an aluminum-magnesium alloy with an alkyl halide in the presence of a nitrogen-containing organic compound to obtain a trialkylaluminum-containing reaction product, and reacting an aluminum-magnesium alloy and an alkyl halide. A highly active, low viscosity composition containing the particulate aluminum alloy and a method for producing the particulate aluminum alloy-containing composition are also described.

An aluminum oxide article containing at least aluminum atoms and oxygen atoms is described. When observed under a transmission electron microscope, a cross section of the aluminum oxide article contains crystallized parts, in which a crystal lattice image is recognizable, and a non-crystallized part, in which no crystal lattice image is recognizable, and has an island-and-sea structure consisting of isolated parts containing the crystallized parts and the continuous non-crystallized part. The isolated parts correspond to island parts in the island-and-sea structure, the continuous non-crystallized part corresponds to a sea part, and a plurality of the island parts are uniformly distributed in the sea part. An aluminum oxide for improving the battery performance of a lithium ion secondary battery, the scratch resistance and hardness of a cured film, and the gas barrier properties of a gas barrier film is provided.

Aluminum oxide article

Provided is a solid polymethylaluminoxane composition which has higher activity when being used as a co-catalyst in olefin polymerization. The solid polymethylaluminoxane composition contains polymethylaluminoxane, trimethylaluminum, and AlO, wherein: (i) the aluminum content is in a range of 36-43 mass %; and (ii) the AlOcontent is in a range of 0.001-10 mol % represented in terms of aluminum.
