Feature
We mainly have two models, 330 and 740, of which 330 is blue-greenish, widely used in cement, color brick and other industries; 740 is blue-redish, widely used in the paint and coating industry.
Application
1. Used as analytical reagent, also used in pharmaceutical industry, pigment preparation and electronic industry.
2. Used as the main raw material of ammonia catalyst.
3. Used as a paint for watercolor, oil paint and ink. The coating industry is used to make anti-rust paint and other primers. Used in the construction industry to color artificial marble and cement floors. The electronic and telecommunications industry is used to manufacture magnetic steel and also used as the cathode plate of alkaline dry batteries. Used for steel flaw detection in machine manufacturing.
4. Used for the coloring of tablet sugar coating and capsules.
5. Used in paints and polishes, etc., used in paints, plastics and building surface coloring.
6. Is a commonly used magnetic material. Special pure ferroferric oxide is used as raw material for audio tape and telecommunication equipment.
7. Natural magnetite is the raw material for ironmaking.
8. It is very hard and can be used as abrasive. It has been widely used in the field of automobile braking, such as brake pads, brake shoes, etc.
9. The field of welding materials has been recognized. The production of welding rods and wires is still in its infancy, and the market prospect is very broad.
10. Because of its high specific gravity and strong magnetism, it has shown good performance in sewage treatment.
11. It is also possible to form a dense layer of ferroferric oxide on the surface of steel through certain chemical reactions, such as the use of sodium nitrite, etc., to prevent or slow down the corrosion of steel.
