1.Fe2O3, also known as iron oxide, iron red, red powder, etc., has the chemical formula Fe2O3, which is soluble in hydrochloric acid and is a triangular red transparent powder. The particles are fine, and the particle size is 0.01 ~ 0.05 μ m. It has a large specific surface area (10 times that of ordinary iron oxide red), has strong ultraviolet absorption performance of chemicalbook, and has excellent light resistance and atmospheric resistance. When the light is cast on the paint film or plastic containing transparent iron oxide red pigment, it is transparent. The relative density is 5.7g/cm3, and the melting point is 1396 ℃. It is a new variety of iron series pigments with unique properties.
2.Orange red to purplish red trigonal powder. Insoluble in water, soluble in hydrochloric acid and sulfuric acid, slightly soluble in nitric acid and alcohol.
1.Used for coloring paint, rubber, plastic, architecture, etc.
2.It is an inorganic pigment used as antirust pigment in the paint industry. It is also used as colorant for rubber, artificial marble and terrazzo, colorant and filler for plastic, asbestos, artificial leather, leather polishing paste, polishing agent for precision instruments and optical glass, and raw material for manufacturing ferrite components of magnetic materials.
3.It is used for magnetic raw materials such as electronic industry, communication machines, televisions, computers, row output transformers, switching power supplies and ferrite cores with high u and high UQ.
4.Used as analytical reagent, catalyst and polishing agent, and also used as pigment ingredient.
5.It is used for coating and icing coloring of various tablets and pills. It is used as magnetic material, pigment, reducing agent, polishing agent, catalyst, etc. it is used for coloring tablets, sugar coating, capsules, etc.
6.Inorganic red pigment. It is widely used for coloring paint, rubber, plastic cosmetics, building fine grinding materials, precision hardware instruments, optical glass, enamel, stationery, leather, magnetic alloy and high-grade alloy steel.
