NbB2 Niobium Boride Powder

NbB2 Niobium Boride Powder

Niobium boride, gray hexagonal crystal

It's called Niobium Boride
The formula is B2Nb
1. product performance:

Niobium diboride (nbb2) is a high covalent refractory ceramic material with 

hexagonal crystal structure. Nbb2 is an ultra-high temperature ceramic (UHTC), 

with a melting point of 3050 ° C, lattice constant: a=0.310nm, c=0.330nm,

 hardness (kg/mm2): 2600. In addition, the relatively low density of 〜 6.97 g / cm3

 and good high-temperature strength make it a candidate for high-temperature 

aerospace applications, such as hypersonic flight or rocket propulsion systems.

2. packaging and storage:

This product is packed in inert gas filled plastic bags, sealed and stored in a dry 

and cool environment. It should not be exposed to the air, so as to prevent 

moisture and oxidation agglomeration, which will affect the dispersion performance

 and use effect; The packaging quantity can be provided according to the customer's 

requirements and sub packed.

3. Synthesis method:

Niobium diboride was synthesized by heating in two stages after mixing element 

boron and element niobium in proportion.

4. Function and application field:

It is used as raw material for fine ceramics and superconducting materials. Among 

the superconducting materials, only NBB has high superconducting transition 

temperature. At the same time, niobium diboride is the raw material of gold 

solder. After the solder is brazed with refractory metal NbN, it has good 

wettability and spreadability, good solder fluidity, strong seam filling ability 

and good weld high-temperature strength.
