High-performance magnetic materials Nano Iron Powder

Iron nanopowder has high SSA and high reactivity, fast degradation rate of pollutants 

The nano-iron powder should be sealed and stored in a dry, cool environment, and packaged for inert gas protection or vacuum packaging.

Superfine nano iron powders is magnetic, high active,widely used as magnetic materials.

Hongwu High active iron nanoparticles(20nm-100nm) is widely used in absorbing materials.

Iron nanopowders is high active, do oxygen passivated on the surface, good spherical shape.

As nano iron particle active is very high, generally we supply in wet powder form, particle size has 20nm, 40nm, 70nm, 100nm.99.9%

For safety ship HW NANO supply 20nm 40nm 70nm iron nano dispersion liquid with Volume pricing.

Zero-valent nano iron magnetic powder for wastewater/sewage treatment     Hongwu International Group Ltd offer a highly diverse range of powder grades with average grain sizes from approx. 20nm to 150nm. We provide technical support in the selection of the powders suitable for specific applications and for questions regarding process optimization.     Zero-valent nano iron powder have certain magnetic, and under the action of magnetic field can be separated easily and quickly from the wastewater solution, can effectively remove chlorinated hydrocarbon, diphenyl ether, aromatic nitro and polycyclic aromatic hydrocarbons fluorene, etc.  The decontamination mechanism of nano iron: 1. The reduction of nano iron     the iron is active metal with reducing power, thus it can directly reduce dye into amino organic matterin in the partial acid aqueous.Because amino organic color looks light, and easy to be oxidized decomposition, so the chroma of wastewater can be reduced. Some heavy metal ions in the wastewater can be reduced by iron. 2. Micro electrolysis     Iron has electrochemical properties. Its electrode reaction product the new ecological [H] and fe2+ can make the oxidizing reduction with many components in wastewater, dyeing assistant agent can be damaged, broken, loss auxochromic ability; It can make the macromolecular material decompose into small molecule intermediates, and make some difficult biochemical degradation of chemical material become handle easily to improve the water biological properties. 3. The coagulation adsorption     Under the condition of partial acid wastewater it will produce large amounts of Fe2+ and Fe3+, when the PH value to alkaline and aerobic,ferric hydroxide hydrogen and ferrous hydroxide floc form, iron hydroxide hydrolysis could also generate ferrous hydroxide complex ion, which all have very strong flocculation performance, so original suspended solids in the waste water, and insoluble substances produced by micro electrolysis and chromaticity of insoluble substance can be adsorption condensation, hence the wastewater got the purification.     Thus, Zero-valent nano iron powder processing wastewater a comprehensive effect of reduction, micro electrolysis, coagulation adsorption.

HW nano material sale high purity bi2o3 nano bismuth oxide for electronic ceramics and piezoresistor use O765: Nano bismuth oxide, particle size 20-30nm,99.5% O766: Nano bismuth oxide, particle size 30-50nm,99.5%       Bi2O3 nano bismuth oxide is an important functional material. The use of bismuth oxide is not only a good catalyst for organic synthesis, ceramic coloring agents, plastic flame retardants, pharmaceutical astringents, glass additives, high refractive glass and nuclear engineering glass manufacturing and nuclear reactor fuel, but also is a kind of important doping powder material in the electronics industry.       Bi2O3 nano bismuth oxide powder is mainly used in the chemical industry (such as chemical reagents, bismuth salt manufacturing, etc.), the glass industry (mainly used for coloring), the electronics industry (electronic ceramics, etc.) and other industries (such as fire paper manufacturing, nuclear reactor fuel. Among them, the electronics industry is the most widely used bismuth oxide industry, mainly used in varistors, thermistors, zinc oxide arrester and CRT, and other fields. If the material from the points, bismuth oxide is mainly used for electronic ceramic powder materials, electrolyte materials, optoelectronic materials, high-temperature superconducting materials, catalysts. Electronic ceramic powder materials the field of electronic ceramics are a mature and dynamic field for the application of bismuth oxide.        Bismuth oxide as an important additive in the electronic ceramic powder material, the purity of the general requirements of more than 99.5%. The main application targets are three categories that are zinc oxide varistor, ceramic capacitors, and ferrite magnetic materials. In the development of electronic ceramics, the United States is one of the top one in the world. While Japan relies on mass production and advanced technology to occupy the world's ceramic market share of 60%. With the nano bismuth oxide research and development and homogenization of manufacturing technology innovation will also greatly promote the electronic ceramic-related components to improve performance and reduce production costs. Bismuth oxide in zinc oxide varistor mainly plays a role in the formation of agents, zinc oxide varistor with high nonlinear voltammetry, the characteristics of the main contributors.
