Characteristic




Niobium diboride (NbB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. NbB2 is an ultra high temperature ceramic (UHTC) with a melting point of 3050 °C. This along with its relatively low density of ~6.97 g/cm3 and good high temperature strength makes it a candidate for high temperature aerospace applications such as hypersonic flight or rocket propulsion systems.




Chemical formula:NbB2

Molar mass:114.526 g/mol

Appearance:grey powder

Density:6.97 g/cm3

Melting point:~3050°C

Boiling point:N/A

Solubility in water:Insoluble

Crystal structure:Hexagonal, hP3 a = 3.085 Å, c = 3.311 Å and c/a = 1.071 Å




Pressureless sintering of NbB2 is possible with sintering additives such as boron carbide and carbon which react with the surface oxides to increase the driving force for sintering but mechanical properties are degraded compared to hot pressed NbB2.
