Amorphous boron nitride (a-BN) layers are used in some semiconductor devices, e.g., MISFETs. They can be prepared by the chemical decomposition of trichloro borazine with cesium or by thermal chemical vapor deposition methods. Thermal CVD can also be...…
Hexagonal BN can be prepared as fibers, structurally similar to carbon fibers, sometimes called "white carbon fiber." They can be prepared by the thermal decomposition of extruded borazine fibers by adding boron oxide in nitrogen at 1800 °C. The mate...…
Cubic boron nitride is produced by treating hexagonal boron nitride at high pressure and temperature, much as synthetic diamond is made from graphite. Direct conversion of hexagonal boron nitride to the cubic form occurs at pressures up to 18 GPa and...…
The graphite-like polymorph of boron nitride, hexagonal boron nitride, h-BN, α-BN, or g-BN (graphitic BN), sometimes called "white graphite," is the most widely used. The hexagonal polymorph is composed of layers of hexagonal sheets analogous to grap...…
What is Boron nitride?Boron nitride is a non-toxic thermal and chemical refractory compound with high electrical resistance and is most commonly available in colorless crystal or white powder form. It is an advanced ceramic material often called "whi...…
Boron nitride nanotubes (BNNTs) have a similar tubular structure as carbon nanotubes in which carbon atoms are replaced entirely by boron and nitrogen atoms, arranged in a hexagonal lattice. Not surprisingly, because of this similarity, both BNNTs an...…
Boron nitride nanotube (BNNT) has a similar tubular nanostructure as carbon nanotube (CNT) in which boron and nitrogen atoms are arranged in a hexagonal network. Owing to the unique atomic structure, BNNT has numerous excellent intrinsic properties, ...…
BN7000: When high purity, binder-less, and the highest temperature capability are required, BN7000 offers the best of all its grades. With a temperature up to 2000° C in inert atmospheres or high vacuum, BN7000 can be used in the most extreme conditi...…
Boron nitride is a high-temperature ceramic that has a structure similar to graphite. Our portfolio of hot-pressed solid materials includes pure hexagonal boron nitride and composites suitable for applications requiring excellent thermal properties c...…
Boron nitride nanoparticles and nanosheets have recently drawn much attention due to their unique mechanical, optical, physical, and chemical properties. They are regarded as interesting materials for various applications, such as boron neutron captu...…
High expectations are placed on aggregate BN powders as high thermal conductivity materials with heat dissipation and insulation properties on the same level as ceramic materials for use in the heat-dissipating insulation sheets of power modules. Hig...…
Hexagonal boron nitride (h-BN) is a white ceramic material with a layered structure similar to graphite. It is a raw material for cosmetics and various industrial applications owing to its good lubricity, heat resistance, electrical insulation proper...…
This article will talk about different types of high-efficient water reducers and the mechanism of superplasticizers.…
The results show that a coating layer is formed on the surface of boron powder after being coated by the coating agent. The pH value of boron powder and water suspension system increases obviously after coating, which is suitable for the pharmaceutic...…
Ascorbic acid (vitamin C), as a building material admixture, has been used in expressways, high-rise buildings, bridges and culverts and other construction projects, can be compounded, is an excellent water reducer additive.…
