Hexagonal Boron Nitride Powder 50 Nano Super Fine 99% Food Grade Cosmetic Grade Cubic Boron Nitride Powder
Hexagonal Boron Nitride:White graphite is another name for hexagonal boron nitride. White graphite is the simplest boron-nitrogen polymer. Similar to the hexagonal carbon network in graphite, nitrogen and boron in hexagonal boron nitride also form hexagonal network layers that overlap each other to form crystals. The crystal is similar to graphite, with diamagnetism and high anisotropy, and the crystal parameters are also quite similar. Boron nitride is mainly used in refractory materials, semiconductor solid-phase doping sources, structural materials of atomic stacks, packaging materials against neutron radiation, rocket engine components, high-temperature lubricants and mold release agents.

Product Description

 



In the expansive field of nanotechnology, Boron Nitride Nanotubes (BNNTs) have emerged as a subject of significant interest due to their unique properties and potential applications. First synthesized in 1995, these structures are similar in morphology to the better-known carbon nanotubes but are composed of boron and nitrogen atoms instead of carbon. This distinct composition endows BNNTs with exceptional mechanical strength, high thermal conductivity, and notable electrical insulation properties.
The diameter of these nanotubes is measured in nanometers, indicating their incredibly small scale and the precision required in their manipulation and use. Unlike carbon nanotubes, BNNTs exhibit transparency and are not affected by changes in chirality, making them versatile in various applications ranging from the optical industry to aerospace and biomedical fields. Their resilience at high temperatures and oxidation resistance also make them suitable for extreme environments.

1. Aerospace: Boron in BNNTs strengthens materials and shields against harmful radiation by effectively absorbing neutrons.
2. Reinforcement: BNNTs enhance the mechanical properties of polymers, ceramics, and metals. For instance, adding them to
aluminum boosts strength and stiffness without excessive weight, useful for automotive and aerospace.
3. Nanoelectronics: Their high thermal conductivity and electrical insulation are ideal for managing heat in densely - packed
nanoelectronic components like semiconductors and sensors.
4. Energy: BNNTs' piezoelectric property, generating electricity from mechanical stress, has potential in energy harvesting devices,
sensors, and actuators.
