Description
Zinc Iron Oxide Micron Powder (ZnFe₂O₄, −325 mesh, 99+%)
Zinc Ferrite Micron Powder is a spinel-structured, zinc–iron oxide–based, multi-component inorganic performance pigment. Its −325 mesh particle size provides homogeneous dispersion and stable processing performance. The product is suitable for demanding industrial applications due to its high heat resistance, light fastness, and weather durability. When combined with organic pigments, it enables the development of green, red, and brown color shades.
