1. Nano metal lubrication additive: add 0.1~0.5% micro/nano bismuth powder to lubricating grease to form self-lubricating and self-repairing film on the surface of friction pair in the friction process, and significantly improve the performance of grease;
2, metallurgical industry: micro nano bismuth powder can be used as iron, steel and aluminum alloy additives, improve the easy cutting performance of the alloy;
3, magnetic material: bismuth thermal neutron absorption cross section is very small and the melting point bottom, high boilingpoint, can be used as a nuclear reactor heat transfer medium;
4, nano alloy: micro nano bismuth powder, small particle size, high purity, high sphericity, low melting point, can be applied to alloy materials, refining the crystal phase structure of alloy materials, improve the mechanical properties of alloy materials, at the same time reduce the sintering temperature of alloy materials.
