摘要： Ultrafine particles of aluminum nitride having a morphologically anisotropic structure of columns, plates, or whiskers such that the ratio of thickness or width to length or the ratio of thickness to width or length of particle is not less than 1 are produced by thermally melting a binary alloy of metallic aluminum and a rare earth element in a nitriding atmosphere containing nitrogen. By this method are produced composite ultrafine particles which substantially comprise ultrafine particles of aluminum nitride having the morphologically anisotropic structure and ultrafine particles of the rare earth nitride which functions as a sintering auxiliary therefor. The composite ultrafine particles or an aggregate thereof are usable as a raw material for the production of a sintered article, a reinforcing material for various metal-based composite materials, a blast powder, and the like.

摘要： An aluminum alloy powder for coating materials and a coating material containing the aluminum alloy powder. The aluminum alloy powder comprises an amorphous aluminum alloy consisting essentially of from 83 to 91% of Al, from 0.5 to 5% of Ca and from 8 to 12% of Ni, all in atom %, and comprising a leaf-shaped particle having a thickness of 0.3 to 3 .mu.m, a minor axis of from 10 to 150 .mu.m, a ratio of the minor axis to a major axis of from 1 to 3, and an aspect ratio which is the ratio of the minor axis to the thickness of from 3 to 100, wherein the aluminum alloy powder is contained in an amount of from 5 to 25 parts by weight based on 100 parts by weight of the total weight of (i) the coating material resin component and (ii) aluminum alloy powder, and the coating material resin component is selected from the group consisting of a water-based synthetic latex and a water-soluble resin. The aluminum alloy powder has a superior dispersibility in a resin in a coating material. When added to a coating material and then coated, the aluminum alloy powder can bring about leafing in a desirable state, so that the coating surface can be effectively covered with the powder. The aluminum alloy powder can impart better hiding power and reflecting properties, even when added in a smaller quantity than conventional powders. Since the aluminum alloy powder is comprised of an amorphous alloy, it does not cause deterioration of reflecting properties, even when used in coating materials containing water-soluble solvents.
