Iron Nanoparticles Nano Fe Powder CAS 7439-89-6

About Iron Nanoparticles Nano Fe Powder:
Nanometer iron particles are submicron particles of the metal iron. Because of their large surface area, they are highly reactive. In the presence of oxygen and water, they rapidly oxidize to form free iron ions. They are widely used in medical and laboratory applications and are also being studied for the remediation of industrial sites contaminated by chlorinated organic compounds.
Nano iron is the iron atoms in accordance with the nanometer level (E-9m) one by one superposition of the formation of iron, there is no difference in physical properties, the difference in chemical properties, for example, ordinary iron will not burn easily, but nano iron can spontaneously ignite in the air; Ordinary iron is weak in corrosion resistance, while nano iron is corrosion resistant, and so on. Tungstenmolybdenummetals is a trusted global Iron Nanoparticles Nano Fe Powder supplier. Feel free to send an inquiry about the latest price of Iron Nanoparticles at any time. 

Product Performance of Iron Nanoparticles Nano Fe Powder:

Iron nanoparticles have a large specific surface area, a strong tunneling effect and a small boundary effect, and also have the general properties of ordinary iron. Iron nanoparticles have a uniform particle size, narrow particle size distribution, high purity and low content of carbon, nitrogen, oxygen, sulfur, phosphorus and other harmful elements. It also has good fluidity, good oxidation resistance and low sintering temperature.

How is Iron Nanoparticles Nano Fe Powder Produced?
The preparation method of nano-iron can be divided into the physical method and chemical methods.
Physical vapor deposition method: also known as evaporation condensation method, is the use of vacuum evaporation, laser heating evaporation, electron beam irradiation, sputtering and other methods to gasification of raw materials or the formation of plasma, and then rapid condensation in the medium. The nanometer particles obtained by this method have high purity, good crystalline structure, and are beneficial to the control of particle size, but the technical equipment is relatively high.
Chemical reduction method: is the use of a certain reducing agent will be metal ferric salt or its oxide reduction of nano iron particles, this method can be divided into solid-phase reduction method, liquid-phase reduction method and gas-phase reduction method.
 
Applications of Iron Nanoparticles Nano Fe Powder:
1. Absorbing material: metal nanoparticles have a special absorbing function. Iron, cobalt, zinc oxide powders and carbon-coated metal powders can be used as stealth materials with millimeter-wave properties for military applications. Iron nanoparticles can be used as infrared stealth material, structural stealth material and mobile phone radiation shielding material.
2. Magnetic medium: the high saturation susceptibility and permeability of nano-iron make it a good magnetic medium, which can be used as the combined structure of a fine magnetic head.
3. High-performance magnetic recording material: nano-iron has the advantages of correction coercoerity, high saturation susceptibility, high specific saturation susceptibility, good oxidation resistance and so on, which can greatly improve the performance of magnetic tape and large capacity hard and soft disk.
4. Magnetic fluid: Magnetic fluid is made of iron, cobalt, nickel and alloy powder, with excellent performance, can be widely used in sealing damping, medical equipment, sound control, light display and other fields.

Storage Condition of Iron Nanoparticles Nano Fe Powder:
The damp reunion will affect Iron nanoparticles dispersion performance and using effects, therefore, this iron powder should be sealed in vacuum packing and stored in cool and dry room and it should not be exposure to air. In addition, the Fe Nanoparticle should be avoided under stress.

Packing & Shipping of Iron Nanoparticles Nano Fe Powder:
We have many different kinds of packing which depend on the iron powder quantity.
Iron nanoparticles packing: vacuum packing, 1kg/bag, 25kg/barrel, or as your request.
Iron nanoparticles shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.

Bismuth Nanoparticles Nano Bi Powder CAS 7440-69-9

About Bismuth Nanoparticles Nano Bi Powder:
Bismuth nanoparticles are a kind of metal nanoparticles with colors from dark gray to black according to the different particle sizes. Bismuth is a silvery, crystalline, brittle metal when freshly produced and it often presents a pinkish tinge in the air. Bismuth is the most diamagnetic element, and its thermal conductivity is lower than any metal except mercury. It has a high electrical resistance and the highest Hall coefficient. Feel free to send an inquiry to get the latest price if you would like to buy Bismuth Nanoparticles Nano Bi Powder in bulk.

How is Bismuth Nanoparticles Nano Bi Powder produced?
The bismuth nanoparticles are synthesized via a solvothermal reduction method based on the chemical reduction of Bi3+ by ethylene glycol acting as the solvent and the reducing agent. Bismuth based nanoparticles were grown starting from a dispersed solution of the bismuth salt.

Application of Bismuth Nanoparticles Nano Bi Powder:

Lubricant additives
Bismuth is still a common additive for industrial lubrication, and it works effectively without causing toxicity or other hazards to the specified compound. When added 0.1% to 0.3% of nano Bi powder to greases in the friction process, the friction surface will form a self-lubricating mask to protect the machine, it will significantly improve the grease performance.
Nuclear heat transfer
The unique mixture of magnetic, thermal and other properties in bismuth nanoparticles makes this powder the best heat transfer medium for nuclear reactors-only the most suitable material can function. As proof of the potential of this field, it is difficult to find more impressive applications.
Bismuth has a smaller thermal neutron absorption cross-section, lower melting point, and higher boiling point, which enable it to be the heat transfer medium used in a nuclear reactor.
Medical imaging agent
Bismuth nanopowder can be used as an effective contrast agent for medical imaging and some forms of cancer treatment, making it one of the most widely studied nanoparticles. Further medical applications are currently being studied and offer great hope.
Metallurgical Industry
Bismuth nanopowders have been widely used in metallurgy In metallurgy, bismuth is an effective alloying agent for the production and connection of certain metals. Nano Bi powder is used as additives during the production of cast iron, steel and Al alloy, which can improve the cutting performance of the alloy.


Storage Condition of Nickel Nanoparticles Nano Ni Powder:
Damp reunion will affect bismuth nanoparticles dispersion performance and using effects, therefore, nano Bi powder should be sealed in vacuum packing and stored in cool and dry room, the nickel nanoparticles can not be exposure to air. In addition, the Bi Nanoparticles should be avoided under stress.

Packing & Shipping of Nickel Nanoparticles Nano Ni Powder:
