Application:
1. The manufacture of metal neodymium NdFeB magnetic materials and strong original.
2. Add the magnesium alloy or aluminum alloy with 1.5% to 2.5% neodymium oxide nanoparticles can improve the performance of high-temperature alloys, air tightness and corrosion resistance, widely used as aerospace materials.
3. neodymium oxide nanoparticles doped yttrium aluminum garnet produce nano shortwave laser beam, is widely used in industry thickness below 10mm thin material welding and cutting.
4. In the medical, neodymium oxide nanoparticles doped yttrium aluminum garnet laser nano-oxide instead of a scalpel is used to disinfect a wound or surgical removal.
5. neodymium oxide nanoparticles are also used colored glass and ceramic materials and rubber products and additives.
