摘要： A neutral paint colorant has a composition comprising approximately 7.0% Color Index Pigment Yellow 42, 2.4% Color Index Pigment Red 101, and 4.0% Color Index Pigment Black 7. A pre-blended mixture of the neutral colorant and a paint base can be blended with a first paint to form a second paint having substantially the same hue and value (lightness) as the first paint, but a lower chroma (brightness).

摘要： A process for the production of a black iron oxide pigment from Fe2O3 hematite iron oxide which may be an impure oxide produced by the “Ruthner” process or by other means, or which may be a mineral hematite. The process may be used to upgrade poor quality synthetic or natural hematite, or to improve their performance as red pigments, by conversion to black pigment with subsequent oxidation of the magnetite so produced back to hematite. The process uses a low temperature aqueous slurry reaction in which the hematite is contacted with a soluble source of Fe(II) ions in the presence of a soluble source of Fe(III) ions in an aqueous alkaline medium to convert the same to Fe3O4.

摘要： Spindle-shaped hematite particles obtained form the spindle-shaped goethite particles, can be prevented as highly as possible from causing destruction of particle shape when subjected to a heat-reduction step for producing magnetic spindle-shaped metal particles and magnetic spindle-shaped metal particles containing iron as a main component produced from the spindle-shaped goethite particles or the spindle-shaped hematite particles as a starting material, exhibit a high coercive force, an excellent particle coercive force distribution, a large saturation magnetization and an excellent oxidation stability, and are excellent in a squareness (Br/Bm) of the sheet due to a good dispersibility in a binder resin.

摘要： One aspect of the invention relates to a blue shade black pigment composition, containing at least iron oxide, chrome oxide, wherein the ratio of iron to chromium is from about 1:1 to about 5:1 by weight; and manganese oxide. Another aspect of the invention relates to a method of making a blue shade black pigment involving combining iron oxide, chrome oxide, and manganese oxide to form a mixture; heating the mixture to a temperature from about 700° C. to about 1,300° C. for a time from about 1 to about 5 hours; and optionally agitating the heated mixture to provide the blue shade black pigment. Yet another aspect of the invention relates to a plastic composition containing a plastic material and a blue shade black pigment composition containing at least iron oxide, chrome oxide, and manganese oxide.
