Product Description
Black Iron Oxide is an inorganic iron-based pigment used as a colorant and iron source in ceramic formulations, particularly in selected glaze systems. Its cost-effectiveness and characteristic black appearance make it a practical option for ceramic applications. During high-temperature firing, it contributes to glaze coloration, with the final shade depending on the firing temperature, kiln atmosphere, and glaze composition.
High-purity grades are also available for applications requiring controlled impurity levels, including specified limits for certain heavy metals. Grade selection should be based on the relevant product specifications and application requirements.

Application Scenarios
Black Iron Oxide, commonly associated with magnetite (Fe₃O₄), is an inorganic pigment used in a variety of industrial applications beyond ceramics.
Industrial Colorants: Used to provide black coloration in selected construction materials, coatings, plastics, and other formulated products. Its suitability depends on the pigment grade and processing requirements.
Cosmetics and Personal Care: Certain synthetic iron oxide pigments are used in cosmetic formulations, including makeup products, where consistent color, moisture resistance, and low color bleeding are important. Only grades that meet applicable cosmetic purity specifications and regulatory requirements should be used.
Protective Coatings: Magnetite and other iron-based pigments may be incorporated into selected industrial coating systems, including protective coatings for metal structures. Corrosion protection depends on the complete coating formulation, surface preparation, and application conditions rather than the pigment alone.
