Overview of iron oxide Fe2O3 powder:
Iron oxide Fe2O3 powder is an inorganic substance with the chemical formula Fe2O3,which is a red or dark red amorphous powder.The relative density is 5 to 5.25, and the melting point is 1565°C (simultaneous decomposition).There are two types:α type(positive magnetic)and γ type (diamagnetic).Insoluble in water,soluble in hydrochloric acid and sulfuric acid,slightly soluble in nitric acid.It has strong hiding power and tinting power,without oil permeability and water permeability.Stable in the atmosphere and sunlight,resistant to polluting gases,high temperature and alkali.The fineness of products produced by the dry process is usually less than 1 μm.Stable to light, heat and air.Relatively stable to acids and alkalis.Strong tinting power.The refractive index is 3.042.The dry-processed products of this product have coarse and hard crystal particles,which are suitable for magnetic materials,polishing and abrasive materials.Wet-processed products have fine and soft crystal particles,which are suitable for coating and ink industries.
Iron oxide Fe2O3 powder application:
What are the applicable scopes of iron oxide Fe2O3 powder?
Iron oxide Fe2O3 powder can be widely used for the coloring of artificial marble and colored cement.Its pigments are watercolor,paint color,paint and rubber,plastic color,and can also be used in the magnetic material industry.
Due to its special superparamagnetism,magnetic iron oxide particles have a wide range of fields,such as giant magnetoresistance,magnetic fluid and magnetic recording,soft magnetism,permanent magnetism,magnetic refrigeration,giant magnetoresistance materials,magneto-optical devices and magnetic detectors.Application prospects.Video tapes usually use acicular iron or iron oxide magnetic ultrafine particles,and nano-iron oxide is a new type of magnetic recording material.Soft ferrites have been widely used in radio communications,radio and television,automatic control,space navigation,radar navigation,measuring instruments,computers,printing,household appliances and biomedical fields.
Iron oxide Fe2O3 powder is widely used as a pigment in high-end automotive coatings,architectural coatings, nti-corrosion coatings and powder coatings.It is a good environmentally friendly paint.The annual consumption of iron oxide pigments in the world exceeds 1 million tons,which is second only to titanium dioxide and ranks among inorganic pigments.Second place. Iron oxide is used as a pigment.It not only maintains the good heat resistance,weather resistance and ultraviolet absorption of ordinary inorganic pigments,but also can be well dispersed in an oily carrier.The paint or ink prepared with it has satisfactory transparency.Due to its high electrical conductivity,the use of iron oxide with semiconductor properties to make coatings can play a role in electrostatic shielding.
Iron oxide Fe2O3 powder is a commonly used colorant in glass production.Iron oxide colored glass can absorb both ultraviolet and infrared,so it is widely used in the manufacture of heat-absorbing glass,sunglasses glass,industrial protective glass and military anti-infrared coatings.At the same time,it has the function of low price,absorbing Heat and ultraviolet rays
In addition,iron oxide pigments are also widely used as colorants and protective agents for wood coatings abroad.Using transparent iron oxide pigments instead of traditional pigments can retain the transparent wood grain of the wood,and its high light resistance makes the color of the furniture lasting.Ultraviolet rays under the sun will decompose wood lignin and destroy the cell structure,leading to wood aging. Nano iron oxide pigments,due to their fine particles and uniform distribution,will not scatter light and absorb ultraviolet rays,so they can protect wood.
α-Fe2O3 powder particles have a huge specific surface area and significant surface effect,making it a good catalyst.Due to the small size of iron oxide particles,the surface area occupies a larger volume percentage,the bonding and electronic state of the surface are different from the bonding and electronic state inside the particles,and the coordination of surface atoms is different,which leads to an increase in iron oxide.Surface active sites.The catalyst made of nano α-Fe2O3 particles has higher activity and selectivity than ordinary catalysts,and has a long life and is easy to operate.Nano α-Fe2O3 has been directly used as a catalyst for the oxidation, reduction and synthesis of high molecular polymers.When used in petroleum refining, it can increase the cracking speed by 1-5 times.Using it as a solid combustion catalyst can make the combustion faster.The burning speed of ordinary combustion agents is increased by 1 to 10 times,which is very beneficial to the manufacture of high-performance rockets and missiles.
Biomedicine and other fields
