How Niobium Boride NibB2 Pulver Is it Produced?
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 + 2 B2O3 + 11 Mg → 2 NbB2 + 11 MgO
In order to enable acid leaching of the unwanted oxide products, Mg is used in reaction. To consume every ounce of niobiumoxide, it is common to require Stoichiometric amounts of Mg as well as B2O3.
Jha and 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 allowed for the formation of nanocrystals NbB2 at 700 °C under argon flow. This involved a reduction in Nb2O5 and NaBH4 to form Nb2O5. The reaction took place using a Molar Ratio M:4 of 1:14 at 700 °C.
Nb2O5 + 13/2 NaBH4 → 2 NbB2 + 4Na(g,l) + 5/2 NaBO2 + 13 H2(g)
Niobium Boride NibB2 powder :
NbB2 ceramic is an ultra high temperature (UHTC), with a melting points of 3050° C. The ceramic has a low density of 6.97 g/cm3 as well as good high-temperature properties. This ceramic is high in thermal conductivity, electrical conductivity, resistance of 25.7Ybcm, and Cte at 7.7Yb106°C1. It also has similar properties to 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. Therefore, the powders are either hot-pressed or spark plasma-sintered. This applies mechanical pressure to the heated part and allows it then be machined. Although these sintering ingredients react with surface oxides, the mechanical properties for NbB2 are lower than hot pressing.
