There is provided a two-phase alloy containing Cr as a major component and including two phases of an austenite phase and a ferrite phase in a mixed state. The alloy has a chemical composition containing: 34-70 mass % of Cr; 17-45 mass % of Ni; 10-35 mass % of Fe; 0.1-2 mass % of Mn; 0.1-1 mass % of Si; and impurities. The total content of the Ni and the Fe is 30-65 mass %.

Provided is a thermal compound composition having heat dissipation and electrical insulation properties, where the thermal compound composition includes a Cu—CuO composite filler having a Cu core and a shell composed of CuO having a whisker crystal structure. The CuO having the whisker crystal structure is prepared by reacting Cu particles in a basic solution so that an outer shell thereof is grown into whisker-shaped CuO.

The invention relates to copper-containing metal pigments, wherein the copper-containing metal pigments have an elemental copper content of at least 50 wt.-%, relative to the total weight of the uncoated copper-containing metal pigment, wherein the copper-containing metal pigments have at least one enveloping metal oxide layer and at least one enveloping chemically non-reactive plastic layer, wherein the sum of the amounts of the at least one chemically non-reactive plastic layer and of the at least one metal oxide layer lies in a range of from 10 to 50 wt.-%, relative to the weight of the uncoated metal pigment, and the weight ratio of the at least one metal oxide layer to the at least one chemically non-reactive plastic layer lies in a range of from 1:2 to 1:20. The invention furthermore relates to a method for producing these pigments and the use thereof.

Provided is a dendritic silver-coated copper powder which is capable of effectively ensuring a contact, while having excellent electrical conductivity by having the surface coated with silver. A silver-coated copper powder according to the present invention is obtained by coating the surface of a copper powder 1, which is an assembly of copper particles 2 and has a dendritic form having a plurality of branches, with silver. Each copper particle 2, the surface of which is coated with silver, is an ellipsoid that has a breadth within the range of from 0.2 μm to 0.5 μm and a length within the range of from 0.5 μm to 2.0 μm. The average particle diameter (D50) of the copper powder 1, which is obtained by coating the surface of the assembly of the ellipsoidal copper particles 2 with silver, is from 5.0 μm to 20 μm.

A composite oxide black pigment has characteristics to absorb visible rays and near infrared rays, and is composed of an oxide of main constituent metals including copper, manganese and iron. In a wavelength region of 400 to 1,000 nm, the composite oxide black pigment has a minimum wavelength, at which a transmittance becomes minimum, in a wavelength region of 600 to 800 nm, a molar ratio of manganese/iron is 3/1 to 30/1, and a molar ratio of copper/(manganese+iron) is 1/2 to 1.2/2. Its sole use makes it possible to obtain a transparent vivid bluish, neutral gray color, and also to maximize an absorption in a near infrared region. It is, therefore, excellent in near infrared absorption characteristics.
