What is the Use of Nano Fe3O4 Powder?

Nano Fe3O4 Powder is an excellent additive for the production of cement and concrete. The nano-sized particle has a filling effect without actively participating in the hydration process. This makes it a great additive for a wide variety of applications. In this article we will discuss its characteristics and applications. 

Applications of Nano Fe3O4 powder

Nano Fe3O4 Powder, a type of magnetic material, has a wide range of applications. It has been extensively studied for its use in concrete, ceramics, metals, and rubber. Its high density and high magnetic properties make it suitable for construction and many industrial processes. Nano Fe3O4 is also known as nanomagnetite. 

Fe3O4 nanoparticles have been tested for their antibacterial activity against four different strains of bacteria. It has been found that they are highly effective against gram-positive and gram-negative bacteria. Although it is not clear why gram-negative bacteria are more sensitive to Fe3O4, this study shows that nanoparticles of Fe3O4 can possess strong antibacterial activity against both types of bacteria. 

Nanometer Fe3O4 powder can be prepared by a simple process involving a polytetrafluoroethylene autoclave. The iron is dissolved in a solution of ethyl alcohol and urea. The mixture is then calcined at 400 degrees Celsius for 1 h. The final product is then collected for further characterization. 

Preparation of Nano Fe3O4 powder

Nano Fe3O4 powders can be prepared by a variety of processes, including electrolysis, chemical vapor deposition, and thermal processing. NPs have high saturation magnetization and good magnetic response. This makes them promising candidates for magnetic separation applications. This material also has high coercivity and is conductive. 

The first step in the preparation of Nano Fe3O4 powder is to prepare a solution of Fe3O4 and DEG. As the solution temperature increases, the iron solution boils. This causes the iron solution to increase in viscosity. The mixture is then centrifuged three times at 14,000 rpm for 12 min. The precipitate is then oven-dried at 70degC. 

XRD analysis shows that the Fe3O4 nanosheets have a hexagonal or triangular structure with edges ranging from 80 to 150 nm. A HRTEM image of the sample shows good crystallinity with interplanar spacing of 0.296 nm. SAED pattern reveals arrays of diffraction points along the direction. 

Characteristics of Nano Fe3O4 powder

The effect of nano-Fe3O4 powder on cementitious composites has been studied. The powder exhibited a filling effect and decreased total porosity, while it did not participate actively in the hydration process. This material has potential for use in cementitious applications. 

Fe3O4 nanoparticles showed good antibacterial activity against four different bacterial strains: E. coli, P. vulgaris, S. aureus, and S. tularensis. The antibacterial activity was more prominent in gram-negative bacteria, while it was less effective against gram-positive bacteria. Moreover, Fe3O4 nanoparticles displayed a high antibacterial activity against Escheriche coli and Xanthomonas. 

A nanometer Fe3O4 powder can be prepared in the laboratory using a process called the urea method. In this process, iron oxide particles with a diameter of 50-100 nm are prepared and the particle size distribution is controlled. A sample of the final product can be tested for its magnetic properties to determine whether or not it contains the magnetite phase. 

Magnetic properties of Nano Fe3O4 powder

A new magnetic nanocomposite, made of Fe3O4 nanoparticles dispersed in PANI, has been synthesized. The powder exhibits excellent magnetic susceptibility and saturation magnetization, and has broad applications in electromagnetic devices. In addition, it demonstrates good microwave absorption behavior. As a result, it is a promising candidate for broadband shielding materials. 

The magnetization of Fe3O4 depends on four factors: size, geometry, and magnetic anisotropy. At room temperature, Fe3O4 is ferrimagnetic, but thermal fluctuations destroy its ferromagnetic alignment and strength. The magnetic properties of Fe3O4 powder change as the temperature increases, leading to a decrease in magnetization and supermagnetic behavior. 

The magnetic properties of Nano Fe3O4 powder were studied using an aqueous phase coprecipitation method. These Fe 3 O 4 nanoparticles have a diameter of approximately 228 nm and a Polydispersity Index (PdI) of 0.402. The smaller the PdI, the more homogeneous the particles are. 

Recyclability of Nano Fe3O4 powder

Nano Fe3O4 Powder is an eco-friendly alternative to conventional pickle liquor. The process involves the use of low-grade iron oxide powder as the raw material, and an alkaline liq as an oxygenant. Once the waste liquor is prepared, it is stirred using a high-speed emulsion machine. The alkaline liquid is then added to the liquor. Afterwards, the mixture is dried under a vacuum for four hours. 

The Fe3O4@Fritillaria NPs were synthesized by hydro-thermal reaction in 0.1 M NaOH (AR grade). After synthesis, the particles were separated by magnets, and the NaOH was replaced with a solution of Mg(NO3)2$6H2O, Al(NO3)3$9H2O, and urea.
