Application fields of nano-bismuth powder: 1. Metal nano-lubricating additive: Add 0.1~0.3% nano-bismuth powder to the grease to form a self-lubricating and self-healing film on the surface of the friction pair during the friction process, which significantly improves the performance of the grease. 2. Metallurgical industry: Nano-bismuth powder can be used as an additive for cast iron, steel and aluminum alloy to improve the free cutting performance of the alloy. 3. Magnetic materials: The thermal neutron absorption cross section of bismuth is very small, the melting point is low, and the boiling point is high. It can be used as a heat transfer medium in nuclear reactors. 4. Other applications.
