amapharamitha Technical
I izici eyinhloko nano-Bi powder was prepared through a special process, high purity, uniform particle size, ball shape, dispersion, oxidation temperature, the sintering shrinkage. Izicelo of metal nano lubricant additive: add 0.1 to 0.3% nano-bismuth powder to grease in the friction process, to friction surface to form a self-lubricating, self-laminating, and significantly improved grease performance.
Metallurgical industry: Nano bismuth powder can be used as cast iron, steel and aluminum additives to improve the alloy’s easy cutting performance.
Magnetic materials: bismuth thermal neutron absorption cross section is small and the melting point, boiling point, heat transfer medium can be used as a nuclear reactor.
