The current technology is directed to an iron-substituted copper aluminum delafossite pigment, as well as a gallate version of the same. In particular, the materials may be defined as iron-substituted copper aluminum delafossite, CuFexAl1-xO2 and the gallate, CuFexGa1-xO2 where X=0.01 to 1.00, for example, CuFe0.15Al0.85O2, and CuFe0.15Ga0.85O2. The pigments are dark-brown to black, absorb most light in the visible spectrum, but have low absorbance and high reflectance in the near-infrared regions, specifically light from about 700 nm-2500 nm.

The present invention concerns agents containing at least one inorganic pigment, one or more oils, and one or more waxes, and also processes for production thereof and their use for coloration of building products, preferably asphalt, bitumen, bituminous mixtures, tar and tar-containing compositions, and also a process for coloration of building products and the building products colored with the agents.
摘要:
The invention relates to metallic effect pigments with coating, comprising a platelet-shaped substrate, where the coating comprises at least one hybrid inorganic/organic layer, the hybrid layer having at least partly an inorganic network that has one or more inorganic oxide components, and having at least one organic component, the organic component being at least partly an organic oligomer and/or polymer which is covalently bonded at least partly to the inorganic network via one or more organic network formers. The invention further relates to a method of producing these metallic effect pigments, and to their use.

摘要:
An anticorrosion ferrite-based pigment, derived from a hydrometallurgical purification process of EAF dust. EAF dust is generated in an electric arc furnace for carbon steel production by processing scrap metal, direct reduced iron and/or pre-reduced hematite, and using CaO-rich slag; from a condensation reaction of metals vapors of Fe, or Zn and of Mn, Mg, Si and/or Al, and suspended CaO particles and oxygen. The pigment contains a non-toxic amount of lead, and includes condensed metal oxides, comprising ferrites MOFe2θ3, M being Zn, Fe, Mn and Mg, and combinations thereof. The condensed oxides have ferrite structures preserved from the EAF dust, and form aggregates thereof. The pigment includes CaO entrapped by the ferrite structures and being partially available to react with humid air and/or water to protect the substrate against corrosion. The pigments are coated or uncoated. They are used for antifouling or paint formulations.
摘要:
A method for producing covered particles, comprising: a mixing step of mixing a fluid containing particles comprising at least one type of substance selected from among metals, metal oxides and ceramics, a silsesquioxane having a functional group with an affinity for carbon dioxide, and supercritical carbon dioxide; and a covering step of reducing pressure of the fluid to gasify the supercritical carbon dioxide, while adhering the silsesquioxane onto the particles, and thereby obtaining covered particles comprising the particles and silsesquioxane covering the particles.
