For magnetic materials and precision polishing

Black nano ferroferric oxide Vk-EF01 is a mixed valence oxide of iron with a melting point of 1597 ℃, insoluble in water and soluble in acid solution. Vk-EF01 has anti-corrosion effect. For example, the blue of steel parts (also known as burning blue and baking blue) is to use the oxidation of alkaline oxidizing solution to form a layer of blue-black or dark blue Fe3O4 film on the surface of steel parts to increase corrosion resistance, luster and beauty.


1 It is used as analytical reagent, pigment preparation and electronic industry.

2 Used as pigment for watercolor, oil color and ink. The coating industry is used to manufacture antirust paints and other primers. The construction industry is used for coloring artificial marble and cement floors. The electronic telecommunications industry is used to make magnetic steel and also as a cathode plate for alkaline dry batteries. Used in steel flaw detection in machine manufacturing.

3 Used for pigments and polishing agents, etc., used for coloring coatings, plastics and building surfaces.

4 Metallurgy, electronics and textile industries, as well as pigments and glass colorants used as catalysts, polishing agents, paints and ceramics.

5 Ceramics, nano-ceramics, composite ceramic substrates, ferrite materials.

6 Anti-ultraviolet material, microwave absorption material.

7. Magnetic sealing, using the magnetism and dark black color of nano Fe3O4 powder, it can make magnetic recording materials, high gradient magnetic separators, microwave absorbing materials, special coatings and electrostatic copying developer

 Packing: 20kg/barrel
