99% 100-200nm Spherical Bismuth Nano Powder

Spec: 100-200nm, 99%

Application for nano bismuth powders:

1. Nano metal lubricating oil additive :  0.1 -0. 3% nano  biamuth powder in lubricating oil , improve the self repair performance.

2. Metallurgy : Nano biamuth powder can be used as cast iron, steel and aluminum alloy additive, improve alloy cutting performance.

3. Magnetic materials: bismuth thermal neutron absorption cross section is small and the bottom of the melting point, high boiling point, can be used as a medium of heat transfer in the reactor.

4. High purity bismuth compound raw material.
