Carbon Nanotubes

HW Carbon Nanotubes available in single, multi walled, COOH an OH fuctioned Functionalized CNts, different diameter, length, and purity you can choose. Widely used in many fields by customers around the world.

 

The carbon nanotubes can be filled with metal, oxide and other substances, so that carbon nanotubes can be used as a mold, first with metal and other substances filled with carbon nanotubes, then carbon layer corrodes, a fine nanoscale conductor wires or a new one-dimensional material has been created , can applied in the future molecular electronic devices or nanoelectronic devices. Some of the carbon nanotube itself can also be used as nano-scale conductor wire. Therefore, the use of carbon nanotubes or related technology to prepare micro wires can be placed on a silicon chip to produce more complex circuits.

 

Hydrogen is considered as the clean energy of the future by many people .Hydrogen itself, however, for it’s low density it’s not convenient to compressed into a liquid storage. Carbon nanotubes’ lightweight and hollow structure make it a good reservoir of hydrogen, the density is even higher than the density of liquid or solid hydrogen. Proper heating, hydrogen can be slowly released.

 

The properties of carbon nanotubes can be used to fabricate many composite materials with excellent properties, such as excellent mechanical properties, good electrical conductivity, corrosion resistance and shielding of radio waves with carbon nanotubes materials. Carbon nanotube composites using cement as matrix has high strength, good impact resistance, anti-static, wear-resistant, high stability properties, difficult to impact on the environment.Carbon nanotubes reinforced ceramic composite materials with high strength, good impact resistance.

 

  • Carbon nanotubes also provide physicists with the finest capillaries to study the capillary mechanism, providing the chemist with the finest nanotube reaction tubes. The tiny particles on carbon nanotubes can influence the electric current shaking frequency of the carbon nanotubes. Based on this, in 1999, Brazil and the United States scientists invented a nanoscale of 10-17kg accuracy, able to weigh the quality of a single virus. Then the German scientists developed a single atom can be measured in the ” Nano-scale. “

nano-alumina Al2O3

By virtue of its special properties, nano-alumina is widely used in chemical and chemical industry, medicine, catalyst and its carrier, ceramics and other fields. In ceramic applications, precision ceramics made by nano alumina powder have the similar metal plasticity and toughness, light weight, in particular, greatly enhance the strength. By adding a small amount of micron or nano-alumina in the conventional ceramic matrix can make the mechanical properties of materials doubled improve the toughness of ceramics to reduce its sintering temperature.

 

As a new composite material and medical materials, nano-alumina Al2O3 can be used as dispersion strengthening and additives, such as cast iron with nano-Al2O3 grinding powder as a metamorphic nucleation, wear resistance can be improved several times. Nano-alumina as a new medical material, has been used to make the bearing force of artificial bone, dental root implants, drug delivery carrier, etc .; also successfully carried out alveolar ridge expansion, maxillofacial reconstruction, orthopedic and repair. As an optical material and surface protective layer of nano-alumina material can absorb ultraviolet light, and in some wavelengths of light excitation can be generated with the particle size of the wavelength of light. Αlpha-Al2O3 can be sintered into a transparent ceramic to use as a high-pressure sodium lamp material; as well as can be used as a compact fluorescent lamp in the protective layer of the phosphor layer; and mostly can made of fluorescent light-emitting materials rare earth phosphor composite to improve lamp life .

 

Hongwu International Group Ltd, with HWNANO brand, can supply nano-alumina powders with high purity and quality. Based on the existing scientific research as production-oriented, closely learning domestic and foreign advanced technology, and constantly improving and enhancing the production process to ensure that providing customers with good quality and stable products. We also can supply customized nano material according to your request. Shall you have any questions, please don’t hesitate to contact us at hwnano@xuzhounano.com.

Nano Zirconia powder

Zirconia powder is also called Zirconium oxide powder. HW nano zirconia powder available in nano size and micron size(70-80nm,0.3-0.5um, 1-3um, YSZ), which has uniform particle size distribution, no hard reunion and good sphericity, size and purity are adjustable according to customer’s requirements.

 

The nano zirconia powder can be used for making metal zirconium and zirconium compounds, and the crucible refractory brick, high-frequency ceramic, ceramic pigment and zirconium salts are mainly used for piezoelectric ceramics, daily-use ceramics, refractory materials and precious metals smelting with brick of zirconium, zirconium tube, crucible, and so on. Also can be used in the production of steel and non-ferrous metals, optical glass and zirconium dioxide fiber.

 

Nano Zirconia powder using as Zirconia structural ceramics material:

1975 Australian R.G.Garvie use calcium oxide as stabilizer had get partially stabilized zirconia, and it’s the first time use zirconium oxide martensite phase transformation toughening effect to increase the toughness and strength, greatly extend the application of the zirconia in the field of structural ceramics.
