Product use

Iron oxide is a kind of inorganic substance, which can be divided into two types: α-type (positive magnetic) and γ-type (diamagnetic). The hiding power and coloring power are very strong, and there is no oil and water permeability. Stable in atmosphere and sunlight, resistant to fouling gases, high temperature and alkali resistance

（1）Iron oxide is used in magnetic materials. Because of its special superparamagnetism, magnetic iron oxide particles have broad application prospects in giant magnetoresistance, magnetic fluid and magnetic recording, soft magnetic, permanent magnet, magnetic cooling, giant magneto-impedance materials, magneto-optic devices, magnetic detectors and so on；

（2）The coating made of iron oxide with semiconductor properties can play the role of electrostatic shielding because of its high electrical conductivity；

（3）Iron oxide is a commonly used colorant in glass production, which is used in the manufacture of endothermic glass, sunglasses glass, industrial protective glasses glass and military anti-infrared coating. At the same time, it has the functions of low price, absorbing hot line and ultraviolet ray；

（4）Iron oxide particles are fine, the volume percentage of the surface is large, the bond and electronic states of the surface are different from those inside the particles, and the coordination of atoms on the surface is different, which leads to the increase of active sites on the surface. The activity and selectivity of the catalyst made of nanometer α-Fe₂O₃ particles are higher than that of the ordinary catalyst, and it has a long life and is easy to operate；

Product advantage

The Fosmande plant can produce products of different particle sizes, such as nanometer level, submicron level and micron level. Iron oxide has micro shapes such as spherical and magnetic spheres. The products that have been industrially produced are 0.2 μm, 0.8 μm, 1 μm, 1.5 μm, 2 μm and 45 μm, all of which can be supplied at tonnage level and can be customized by customers with other granularities. In order to meet the needs of the laboratory, we generally have packaging specifications such as 100 g, 250 g, 500 g, 1 kg, etc., in order to meet the needs of laboratory research users, and we can customize the packaging specifications according to the quantity of materials supplied by customers.
