boron nitride - wikipedia

Boron nitride - Wikipedia

Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.

Synthesis of cubic boron nitride thin films on silicon

Cubic boron nitride (cBN) synthesis has gained lot of interest during the past decade as it offers outstanding physical and chemical properties like high hardness, high wear resistance, and chemical inertness. Despite of their excellent properties, every application of cBN is hindered by high compressive stresses and poor adhesion. The cost of equipment is also high in almost all the

Boron Nitride (BN) - Properties and Information on Boron

Boron nitride (BN is a synthetic material, which although discovered in the early 19 th century was not developed as a commercial material until the latter half of the 20 th century. Boron and nitrogen are neighbours of carbon in the periodic table - in combination boron and nitrogen have the same number of outer shell electrons - the atomic radii of boron and nitrogen are similar to that of

Effects of Defective Boron Nitride Additives on Lithium

The lithium-ion conductivity and hydrogen-desorption properties of lithium alanate (LiAlH4)/boron nitride (BN) composites were investigated. The effects of boron nitrides with different structures (hexagonal (h-BN), turbostratic (t-BN), and cubic (c-BN)) on the properties were demonstrated. Compared with milled LiAlH4, the ion conductivity was improved in the h-BN and t-BN composites. Among

Magnetic Properties of Fully Bare and Half-Bare Boron

We calculate the electronic structures of the fully bare and half-bare zigzag-edged boron nitride nanoribbons by using density functional theory. We find that the ground states of both the fully bare boron nitride nanoribbons and the boron nitride nanoribbons with a bare N edge and a H-terminated B edge are half-metallic. The alignment of the spin at the bare B edge is antiferromagnetic, while
