Various Applications of Boron Nitride powder

Hexagonal boron nitride is a kind of loose white powder, similar to the properties of graphite, which has known as the “white graphite”. It has good electrical insulation, thermal resistance and chemical resistance; anti-oxidation temperature can up to 900 ℃. Because hexagonal boron nitride has low coefficient of thermal expansion and high thermal conductivity, its thermal shock resistance is excellent.

Solid Boron Nitride with a variety of excellent performance that can be widely used in high-voltage high-frequency electric insulators and plasma arc, automatic welding temperature frame coating, high frequency induction furnace materials, semiconductor phase admixture, atomic reactor construction materials, packaging materials to prevent neutron radiation, radar transfer window, the media radar antenna and composition of rocket engines and so on.

Hexagonal boron nitride is not only a good conductor of heat, but also the typical electrical insulator. HBN has excellent chemical stability. For most molten metals, such as steel, stainless steel, Al, Fe, Ge, Bi, Cu, Sb, Sn, In, Cd, Ni, Zn, etc., it is neither wetting nor acting with each other. Therefore, it is used as a high temperature thermocouple protection kits, molten metal crucibles, containers, liquid metal pipeline, pump parts, mold steel and high-temperature electrical insulation materials. Hexagonal boron nitride (HBN) has a high thermal conductivity, low dielectric constant and dielectric loss, reliable electrical insulation properties, low coefficient of thermal expansion, good thermal shock resistance, excellent processing performance, for most metals are not invasive, light, infrared and microwave-transparent, and has very high heat resistance, excellent performance, which is an important aerospace materials that has been widely used in launch vehicles, spacecraft, missiles, satellites and other spacecraft radio system. This new material has many excellent properties with hardness better than diamond crystal, tougher than commercial carbide, and cubic boron nitride anti-oxidation temperature higher than the single crystal itself, HBN is expected to become a new generation of steel materials processing industry in the tool material so there is no doubt that it has broad application prospects.

We Hongwu International Group Ltd., a high-tech enterprise that can manufactures hexagonal boron nitride powder with high purity and quality and particle size varying from 100nm to 5um. Should you have any needs or questions about HBN, please don’t hesitate to contact us.

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. “

Application of Nano-silver Antibacterial Agent

Nanotechnology is the 21st century’s most promising emerging technology, widely used in information, biological, pharmaceutical, chemical, aerospace, energy, defense and other fields, which has huge market potential. Nanoparticles are particles in the particle diameter between 1~100nm, also referred to as ultrafine particles. Excellent performance of nanomaterials depends on its unique microstructure. Nanoparticles having a small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect, which shows a material different from conventional thermal, optical, electrical, magnetic, catalytic and sensitive properties.

Nano-silver material has a very stable chemical and physical properties that has a very excellent performance in many aspects of electrical, optical and catalytic, now widely used in many fields of ceramic materials, environmentally friendly materials and coatings. When silver particles are embedded in the different substrates, the original material exhibits different electrical and optical properties. Nowadays, study on silver nanoparticles is still a hot spot with a wide application. At present, nano-silver antibacterial nonwoven fabric as raw material of a variety of medical, health, household and industrial use antibacterial products have been listed.

On the domestic market, the successful launch of nano-silver wound paste, paste nanosilver burns and has dual protective effect of nano silver antimicrobial masks. In recent years, a seriou of products have developed in market, such as a nano-silver antibacterial sanitary napkins, sanitary pads nano-silver, nano-silver antibacterial diapers etc. The newly developed nano-silver antibacterial deodorant antibacterial socks and various types of air filter media, antibacterial wipes, antibacterial mop, antibacterial wipes and the like. Today because of people’s increasing emphasis on health care, nanosilver has excellent antimicrobial efficacy of its products and more widely. Nano silver can also be applied to antibacterial interior wall paint.

Antibacterial interior wall paint can effectively inhibit and kill harmful bacteria in the environment, reduce environmental microbiological hazards on the human body, thus achieving the purpose of the clean environment, the protection of human health, improve the living environment of great significance. Inorganic antibacterial agent is present advantages in safety, durability, broad-spectrum antimicrobial resistance, heat resistance, etc., to overcome the disadvantages of conventional paint mildew fungicides greater toxicity, a soluble, heat, poor durability, and increasingly draw people’s attention.

Currently there are natural antibacterial materials antibacterial materials, organic materials and inorganic synthetic antibacterial antibacterial materials.

In general, natural antibacterial material has the advantage of high security, but it generally short-lived, poor heat resistance, easy re-processing; synthetic organic antibacterial materials having a wide range antibacterial, sterilization speed, etc., but in general it side effects is relatively large, easy hydrolysis, life is short; nano-silver is an inorganic antibacterial material, from the current situation of people in research and development of nano-silver watch, which has a high safety, good heat resistance, antibacterial wide range continuous sterilization of long shelf life and other advantages.

It is precisely because of the nano silver antimicrobial material having the above characteristics and quantum effects of nanomaterials itself and a small effect size and great specific surface features, it attracts so many researchers to so researches and development.
