What is Iron Oxide Powder?

Ferric oxide, also known as iron red or red powder, has the chemical formula Fe2O3. It is a red transparent powder with a trigonal crystal system and is soluble in hydrochloric acid. The particles are fine, with a size of 0.01 to 0.05 μm and a large specific surface area. It has strong ultraviolet absorption, as well as excellent light and atmospheric resistance. When used in paint or plastic, it appears transparent when light is projected onto it. It has a relative density of 5.7g/cm3 and a melting point of 1396℃, making it a unique type of iron pigment.

Iron oxide pigments are known for their excellent coloring properties, especially in ceramics where they are used to prepare glazes of various colors. The different colors of iron oxide are due to the varying prices of iron ions. For example, ferric oxide (Fe2O3) is red, ferrous oxide (FeO) and ferric oxide (Fe3O4) are black. Additionally, the color of iron oxide can change depending on the firing atmosphere used in the manufacturing process of ceramics. In an oxidizing flame atmosphere, the color can change from yellow to reddish brown to grape red to brown. In a reducing atmosphere, the color can change from blue to gray. These changes are a result of the dynamic balance of Fe2+ and Fe3+ in the glaze layer.

Iron Oxide Powder Uses

  1. Iron Oxide Powder is an inorganic pigment commonly used in the paint industry for its anti-rust properties. It is also utilized as a colorant in various products such as rubber, artificial marble, and floor terrazzo. Additionally, it serves as a filler for plastics, asbestos, and artificial leather, as well as a polishing agent for precision instruments and optical glass. Furthermore, it is a key component in the manufacturing of magnetic material ferrite components.
  2. In the electronics industry, Iron Oxide Powder is used as a ferrite core in communication equipment, televisions, and computers, as well as in line output transformers, switching power supplies, and high U and high UQ materials. It also finds application as an analytical reagent, catalyst, and polish, and is used for coloring the outer coating of various tablets and pills.
  3. Moreover, Iron Oxide Powder is employed in the preparation of reducing agents, polishing agents, and catalysts, and is utilized as a pigment in anti-rust paint. It is also utilized as an edible red pigment in various food products and is commonly used for transparent coloring of coins, paints, inks, and plastics.
  4. Overall, Iron Oxide Powder is a versatile material with a wide range of applications, including coloring paint, rubber, plastic, cosmetics, construction materials, and more.

Iron Oxide Powder How to Reduce Viscosity

Iron Oxide Powder has long been a challenge for coating company formulators due to its unique particle morphology and surface chemical properties, leading to high viscosity in most coating systems. Unlike other equiaxed crystal systems, iron oxide has a needle-shaped crystal structure, resulting in greater anti-flow properties and higher viscosity.

The selection of the appropriate pigment is crucial in controlling viscosity, especially with the shift towards high-solids, low-VOC coatings. Lower viscosity ferric oxide pigments are in demand to meet these requirements.

CN201711389688.7 proposes a method to quickly reduce the viscosity of Iron Oxide Powder without the addition of metal ions or oxides. In a stainless steel reaction barrel, Iron Oxide Powder filter cake material is mixed with water to form a slurry. The slurry concentration is controlled, and a dilute alkali solution is added dropwise while maintaining a specific pH and stirring speed. Samples are taken periodically for analysis and testing, followed by drying and crushing for further analysis.

This method offers a solution to the viscosity challenge posed by Iron Oxide Powder, providing formulators with greater flexibility in their coating formulations.

Iron Oxide Powder Production Method

There are two main preparation methods for iron oxide red: the wet method and the dry method. The wet process involves reacting a 5% ferrous sulfate solution with an excess of caustic soda solution, introducing air at room temperature to form a reddish-brown ferric hydroxide colloidal solution, and then using this as a crystal nucleus for deposited iron oxide. The dry process, on the other hand, reacts nitric acid with iron flakes to produce ferrous nitrate, which is then crystallized, dehydrated, dried, ground, and calcined at 600-700°C for 8-10 hours to obtain iron oxide red.

The wet method results in fine crystals and soft particles, making the product suitable for use as pigments, while the dry method produces large crystals and hard particles, making it suitable for use as magnetic materials and polishing and abrasive materials. Iron oxide yellow can also be used as a raw material, and iron oxide red can be produced by calcining at 600-700°C. This process involves the reaction of 4Fe(NO3)3 to produce 2Fe2O3, along with NO2 and O2 as byproducts. Additionally, Fe2O3 can be obtained by heating Fe2O3 with water.
