How is Niobium Boride NibB2 Pu Created?
NbB2 could be created by the stoichiometric reacting of components elements. This react allows for precise stoichiometric controls of materials. Also, metallothermic reduce can be used in order to reduce Nb2O5 (or NbO2) into niobium disboride. The reaction is described in the next section.
Nb2O5 + 2 B2O3 + 11 Mg → 2 NbB2 + 11 MgO
The reactant is Mg to permit acid leaching. Stoichiometric excesses Mg/B2O3 may be required to consummate all of the available Niobium oxide.
Jha and his colleagues suggested borothermal reduction of NbO2 via solid state reaction to produce nanorods (20 800 nm2).
Ran and his colleagues suggested a modified borothermal reduction of molten salt. Ran and coworkers used Nb2O5 in combination with elemental boron (61 nm).
Zoli’s method of synthesizing NbB2 nanocrystals was successful. It involved reducing Nb2O5 by NaBH4 for 30 min at 700°C under argon flow.
Nb2O5 + 13/2 NaBH4 → 2 NbB2 + 4Na(g,l) + 5/2 NaBO2 + 13 H2(g)
Niobium Boride NibB2 Pulver
NbB2, an ultrahigh temperature ceramic (UHTC), is a high-temperature material with a melting value of 3050° C. The ceramic exhibits high thermal conductivity as well as electrical conductivity (resistivity at 25.7°Cm, Cte at 7.7°C1) and the same properties that titanium diboride.
It is common to heat press or spark plasma-sinter NbB2 pieces (mechanical pressure is applied on the heated powder). The parts then get machined. NbB2 has a high covalentity and is therefore difficult to melt. This sintering agent reacts with surface oxides and increases the sintering strength. However, NbB2’s mechanical characteristics decreases when hot pressing is used.
