What is Acicular Gamma Fe2O3 Powder?
Gamma-phase iron oxide, also known as gamma iron oxide, has the chemical formula Fe2O3, which is a black or dark brown crystal with stronger magnetic properties.
Fe oxide or iron trioxide with the general formula Fe2O3 is an inorganic compound known to be one of the three main iron oxides naturally present in a mineral called magnetite. When iron oxide is used as a suspension in solutions and applications in the fields of biomedicine, agriculture, and the environment, it has unique supermagnetic properties and easy separation methods. The advantage of powdered iron oxide is that it can be modified with various inorganic and organic compounds (such as starch, polyelectrolyte, and non-ionic detergent) according to its main surface chemical potential to be used for more applications. Magnetic iron oxide is used in biomedical applications by applying an external magnetic field.
Iron oxide is a compound with ferromagnetic properties. When placed in an external magnetic field, the compound is magnetic. When obtained in a controlled size and crystal morphology, this property proves to be the desired characteristic. Iron oxide fine particles have become the focus of attention due to their low toxicity, magnetic properties, and convenient separation methods in medical diagnosis and magnetic resonance imaging (MRI). The application of iron oxide on the macro scale and its reactivity are decisive factors. Still, they exhibit spontaneous combustion when available in smaller sizes in the micron and nano scales. Iron oxide is a semiconductor material with a negative temperature efficiency of resistance.

How is Acicular Gamma Fe2O3 Powder produced?
The main methods of producing gamma-phase iron oxide include thermal decomposition and hydrothermal methods.
Thermal Decomposition: This method usually involves mixing iron salts, oxidizing agents and surfactants, and then heating them to 500 to 700°C. Within this temperature range, the mixture undergoes a series of reactions that ultimately produce gamma-phase ferric oxide.
Hydrothermal: In this method, on the other hand, iron salts, sodium hydroxide and surfactants are mixed and then reacted under high temperature and pressure conditions. By this method, gamma phase ferric oxide can also be obtained.
Application of Acicular Gamma Fe2O3 Powder:
Gamma phase iron oxide, also known as gamma iron oxide or ferromagnetite, is a magnetic iron oxide species with a gray or black color and a cubic crystal structure. Due to its unique structure and properties, gamma-phase iron oxide has been widely used in many fields.
For magnetic materials: Gamma-phase iron oxide has high magnetic properties, so it is commonly used in the preparation of magnetic materials such as high-density storage media, energy storage devices and medical image contrast agents. In addition, due to its special superparamagnetism, it also has broad application prospects in giant magnetoresistance, magnetic liquid, magnetic recording, soft magnetism, permanent magnetism, magnetocooling, giant magnetic impedance materials, as well as magneto-optical devices, magnetic detectors and so on.
Catalyst: Gamma-phase iron oxide can be used in organic synthesis, water treatment, waste gas treatment and other fields as an efficient catalyst.
Environmental protection: Gamma-phase iron oxide can also be used in the field of desulfurization, removal of pollutants and other environmental protection areas, helping to reduce environmental pollution.
