## Synthesis

Sintering powdered niobium and phosphorus:

[math]\ce{ 4Nb + P4 -> 4NbP }[/math]

## Physical properties

The compound is a unique material combining topological and conventional electronic phases. Its superfast electrons demonstrate extremely large magnetoresistance, so NbP may be suitable for use in new electronic components.[2]

Niobium phosphide forms dark gray crystals of the tetragonal system, space group I 41md, cell parameters a = 0.3334 nm, c = 1.1378 nm, Z = 4.[3]

It does not dissolve in water.

Niobium phosphide, like tantalum arsenide TaAs, is a topological Weyl semimetal.[4][5]

## Uses

The compound is a semiconductor used in high power, high frequency applications and in laser diodes. [1]
