Niobium Boride NbB2 Powder


NbB2 can easily be made by the stoichiometric interaction between constituent elements. In this example, Nb is combined with B. This allows for exact stoichiometric control over the materials. The metallothermic method can also be used for the reduction of Nb2O5 and NbO2 into niobium boride. These are inexpensive precursor materials that can be used to react with niobium diboride according the following:

Nb2O5 + 2B2O3 + 11Mg – NbB2+ 11 MgO

In order to enable acid leaching of the unwanted oxide products, Mg is used in reaction. Stoichiometric amounts of Mg, B2O3, and other reactants are sometimes required in order for niobium to be consumed fully.

Jha and his colleagues proposed the borothermal reduction NbO2 by elemental Born using solid-state reaction. This allowed for nanorods to be made (40×800 nm2).

Ran and colleagues proposed a variant of the borothermal reaction in molten sea salt. Ran used Nb2O5 to create nanocrystals (61 nm).

Zoli’s reaction produced nanocrystals NbB2 by reducing Nb2O5 and NaBH4 under 700°C. This was done for 30 minutes with argon flow.

Nb2O5 + 13/2 NaBH4 – 2 NbB2 + 4Na(g,l) + 5/2 NaBO2 + 13 H2(g)


Niobium Boride NbB2 Powder


NbB2 ceramic is an ultra high temperature (UHTC), with a melting points of 3050deg C. The ceramic’s low density, 6.97g/cm3, and high high-temperature resistance make it suitable for high-temperature aerospace applications like hypersonic flight. This ceramic is high in thermal conductivity, and electric conductivity. (Resistivity: 25.7 OYbcm; Cte 7.7 Yb10, -6degC-1). It shares the same properties with titanium diboride.

The NbB2 part is usually heated pressed, spark plasma sintered or hot pressed. Mechanical pressure is then applied to the powder. Finally, it’s machined into form. NbB2 is difficult to sinter due to its covalency with surface oxides. The powders are then heated or spark plasma sintered. Although these sintering ingredients react with surface oxides, the mechanical properties for NbB2 are lower than hot pressing.
