The nitridation or ammonolysis of boron trioxide produces hexagonal boron nitride. H-BN parts can be made by hot-pressing with subsequent machining; the machining cost is low due to the mechanical hardness similar to graphite. The parts are made from...…
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...…
Hexagonal BN (h-BN) is the most widely used polymorph. It is a good lubricant at low and high temperatures (up to 900 °C, even in an oxidizing atmosphere). H-BN lubricant is particularly useful when graphite's electrical conductivity or chemical reac...…
What is Boron nitride?Boron nitride can be doped p-type with beryllium and n-type with boron, sulfur, silicon, or if co-doped with carbon and nitrogen. Both hexagonal and cubic BN are wide-gap semiconductors with band-gap energy corresponding to the ...…
Heated gloves, bracelets, and even rings are potential applications for highly conductive titanium carbide (MXene). Titanium carbide is a two-dimensional material composed of alternating atomic layers of titanium and carbon. In a new study,…
What is Fumed Silica?Since its first production in the early forties of this century, fumed silica has found widespread use in industrial applications. Due to its pyrogenic manufacturing process by combustion of silicon tetrachloride in an oxygen-hyd...…
It is a liquid that is 60 percent aqueous and neutral or weakly acidic. About C8 Alkylglucoside It is a liquid that is 60 percent aqueous and neutral or slightly alkaline. It has excellent permeability. The wettability is good, especially in an al...…
