High Purity Iron Oxide Fe2O3 Powder CAS 1309-37-1,99.9%

Description of Iron Oxide Fe2O3 powder：

Iron sesquioxide is a common iron oxide, also known as iron oxide or rust. It is a reddish brown powder that usually absorbs water easily in the air and turns rusty red. The following are the main properties of iron sesquioxide:

Physical property

Iron sesquioxide is a reddish-brown amorphous powder, usually with some pink or brown tint. Its particles vary in size, with some larger and some smaller. The structure of iron trioxide is more complex and can be seen as a mixture of ferrous oxide (FeO) and iron oxide (Fe2O3).

Chemical property

Iron sesquioxide is an alkaline oxide that reacts with acids to form corresponding iron salts and water. For example, It can also react with a base to form the corresponding ferrite. In addition, iron sesquioxide can also be reduced to metallic iron, such as by reacting with carbon monoxide at high temperatures.

Stability

Iron sesquioxide easily absorbs water in the air and turns rusty red because its surface is very absorbent. It is stable at room temperature but easily decomposes into ferric oxide and oxygen at high temperatures. In addition, iron sesquioxide can also be oxidized to iron sesquioxide and oxygen.

Iron oxide red production method

Iron oxide red is a common iron trioxide product, mainly used in coatings, paints, pigments, and other fields. Its production method is based on iron-containing waste (such as scrap iron, iron ore, etc.) as raw materials through oxidation reactions, high-temperature roasting, and other steps to prepare. 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. It is then roasted at high temperatures to convert the iron oxide into iron oxide red. The method has the advantages of a 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 trioxide by heating ferric hydroxide wet method. 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 decomposes ferric hydroxide into ferric trioxide through high-temperature roasting. The method has the advantages of a simple process, but the product purity is low, and it is mainly used in the general industrial field.

Ferrous oxalate heating process

The heating process of ferrous oxalate is a method to prepare ferrous trioxide 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 sesquioxide. 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 producing iron sesquioxide 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 metallic iron through the electrolytic process, and then converts metallic iron to iron trioxide 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 to iron sesquioxide through a chemical reaction. The method takes iron-containing raw materials (such as pyrite, zinc, etc.) as raw materials react with oxygen or water vapor at high temperatures 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.

Pigments and coatings

Iron oxide is a common red pigment widely used in coatings, paints, pigments, and other fields. It has the advantages of good stability, strong weather resistance, and corrosion resistance, which can effectively protect the surface of the coating and improve the weather resistance and service life of the coating. At the same time, iron sesquioxide can also be used as a pigment additive for the manufacture of various colors of coatings and paints.

Ceramics and glass

Iron oxide can be used to make a variety of ceramic and glass products. In ceramic manufacturing, iron sesquioxide can be used as a colorant and glaze additive to change the color and surface properties of ceramics. In glass manufacturing, iron trioxide can be used as a clarifying agent and a shading agent to improve the transparency and quality of glass.

Catalyst field

Iron oxide Iron sesquioxide can be used to catalyze a variety of chemical reactions. In addition, iron trioxide can also be used as a waste gas treatment agent for the treatment of harmful substances in industrial waste gas.

Electronic industry field

Iron 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 a dielectric material, electrode material, conductive material, 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

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

Agricultural field

Iron oxide can be used in agriculture, such as as a pesticide additive, fertilizer additive, and so on. In pesticides, iron trioxide can be used as insecticides and fungicides, etc., with better insecticidal and bactericidal effects. In fertilizers, iron trioxide can be used as iron fertilizer and trace element fertilizer, etc., to help improve the quality of crops.

Biomedical field

Iron oxide can be used in biomedical fields, such as a drug carrier, drug sustained-release agent, etc. By combining with the drug, the iron trioxide can wrap the drug in the carrier and slowly release the drug ingredients, thus achieving better therapeutic results. In addition, iron sesquioxide can also be used in the preparation of biological materials, medical devices, and other fields.
