High Purity Iron Oxide Fe3O4 Powder CAS 1317-61-9,99.9%

Description of Iron Oxide Fe3O4 Pulver：

Physical property： Ferric oxide is a black solid with a metallic luster and magnetic properties. Its crystal structure is formed by the combination of two Fe2O3 and FeO and, therefore, has special magnetic and electrical properties. The particle size and form of ferric oxide vary depending on the preparation method and conditions and can be in powder, granular, or block form.

Chemical property： Iron tetroxide has a strong oxidizing ability and can react with reducing agents to produce iron and oxygen. For example, reacting with hydrogen to produce iron and water and reacting with carbon monoxide to produce iron and carbon dioxide. In addition, ferric oxide can also react with acid to form the corresponding iron salts and water.

Magnetic property： Iron tetroxide is magnetic and attracts iron objects. Its magnetism is temperature-dependent, having strong magnetism at low temperatures and weakening magnetism at high temperatures. This magnetic property makes ferric oxide have a wide range of applications, including information storage and electromagnetic shielding.

Electrical property： Ferric oxide is a semiconductor material with excellent electrical properties. Its resistivity varies with temperature, with higher resistivity at low temperatures and lower resistivity at high temperatures. In addition, ferric oxide can also be used to manufacture various electronic components, such as integrated circuits, capacitors, transformers, etc.

Stability： Iron tetroxide is stable at room temperature but is easily decomposed into iron and oxygen at high temperatures. It is easy to absorb water in the air and become rust, but it can remain stable in a vacuum.

Iron oxide red production method

Iron oxide red is a common production method of ferric oxide, which is prepared from iron-containing waste (such as scrap iron, iron ore, etc.) through oxidation reaction and high-temperature roasting. The specific process is as follows: the iron-containing waste is crushed and mixed with acid substances such as nitric acid, and the oxidation reaction is carried out at a certain temperature to generate iron trioxide and water. After high-temperature roasting, the iron oxide is converted into iron oxide. The method has the advantages of a wide source of raw materials, simple process, and low cost, but the product purity is low, and it is mainly used in the general industrial field.

Decomposition of iron hydroxide by heat

The thermal decomposition of ferric hydroxide is a method to prepare ferric tetroxide by heating ferric hydroxide wet. The method takes iron-containing wastewater (such as electroplating wastewater, mine wastewater, etc.) as raw materials. It obtains ferric hydroxide through precipitation, filtration, and other steps, and then through high-temperature roasting, the ferric hydroxide is decomposed into ferric tetraoxide. This method has the disadvantages of low product purity and uneven particle size. Still, the raw material source is wide, and the cost is low, so it is suitable for some special applications.

Ferrous oxalate heating process

The heating process of ferrous oxalate is a method to prepare ferric oxide by heating ferrous oxalate. The method uses ferrous oxalate as raw material and is heated at a certain temperature to decompose ferrous oxalate into ferrous tetroxide. This method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.

Electrolytic method

Electrolysis is a method of preparing ferric tetroxide by electrolysis of an iron-containing solution. The method takes iron-containing solution (such as ferrous sulfate, ferrous chloride, etc.) as raw material, reduces ferrous ions in the solution to ferrous metal through the electrolytic process, and then converts ferrous metal into ferrous tetroxide through an oxidation reaction. The electrolysis method has the advantages of high product purity and uniform particle size, but it also has some disadvantages, such as high cost and high equipment requirements.

Chemical method

The chemical process is a method of converting iron-containing raw materials into ferric tetroxide by chemical reaction. The method takes iron-containing raw materials (such as pyrite, zinc, etc.) as raw materials that reacts with oxygen or water vapor at high temperature to produce ferric oxide and corresponding oxides. The chemical method has the advantages of low cost and simple process, but it also has some disadvantages, such as low product purity and uneven particle size.

Magnetic material field

Ferric oxide has strong magnetism and can be used to manufacture magnetic materials, such as magnetic film and magnetic powder. These materials can be used in information storage, electromagnetic shielding, electronic components, and other fields. For example, ferric oxide magnetic powder can be used to manufacture magnetic storage media such as audio tapes and video tapes. It can also be used to manufacture electromagnetic shielding materials.

Catalyst field

Ferric oxide can be used as a catalyst to catalyze various chemical reactions. In addition, ferric oxide can also be used as an exhaust gas treatment agent for the treatment of harmful substances in industrial waste gas.

Electronic industry field

Ferric oxide can be used to manufacture various electronic components, such as integrated circuits, capacitors, transformers, etc. In these components, ferric oxide can be used as dielectric materials, electrode materials, conductive materials, etc., with good electrical properties and stability. In addition, iron oxide can also be used to manufacture new energy devices such as solar cells.

Environmental protection field

Ferric oxide can be used to treat pollutants such as waste gas, wastewater, and waste residue. For example, in the treatment of waste gas, ferric oxide can be used as a catalyst to convert harmful gases into harmless substances. In the treatment of wastewater, ferric oxide can be used to kill bacteria and viruses. In the treatment of waste residues, ferric oxide can be used to extract valuable metallic elements. In addition, ferric oxide can also be used in soil remediation and other fields.

Biomedical field

In recent years, the application of ferric oxide in the biomedical field has also been widely studied and developed. For example, ferric oxide can be used as a drug carrier, drug sustained-release agent, etc., for drug therapy. By combining with the drug, ferric oxide can wrap the drug in the carrier and slowly release the drug ingredients, thus achieving better therapeutic results. In addition, ferric oxide can also be used in the preparation of biological materials, medical devices, and other fields.

Iron and steel industry

In the iron and steel industry, iron oxide can be used as an additive to steel products to improve the performance and hardness of steel. By adding ferric oxide, the wear resistance, corrosion resistance, and other mechanical properties of steel can be improved. In addition, ferric oxide can also be used for anti-corrosion treatment and coating preparation of steel surfaces.

Architectural coatings

Ferric oxide can also be used as a pigment and preservative in architectural coatings. Adding ferric oxide to the coating can make the coating have good weather resistance and corrosion resistance, but it also can improve the adhesion and wear resistance of the coating. In addition, iron oxide can also be used in combination with other pigments to prepare various colors of paint.
