Applications:

1. Additives for steel and non-ferrous alloys. FeCr alloys usually contain 0.5-4% yttrium, and yttrium can enhance the oxidation resistance and ductility of these stainless steels; after adding an appropriate amount of yttrium-rich mixed rare earth to MB26 alloy, the overall properties of the alloy are significantly improved, which can replace some medium-strength aluminum The alloy is used in the force-bearing components of the aircraft; adding a small amount of yttrium-rich rare earth to the Al-Zr alloy can improve the conductivity of the alloy; the alloy has been used by most wire factories in China; adding yttrium to the copper alloy improves the conductivity. and mechanical strength.

2. Silicon nitride ceramic materials containing yttrium 6% and aluminum 2% Chemicalbook can be used to develop engine parts.

3. Use a 400-watt NdYAG laser beam to drill, cut and weld large components.

4. Electron microscope fluorescent screen composed of Y-Al garnet single wafer has high fluorescence brightness, low absorption of scattered light, and good resistance to high temperature and mechanical wear.

5. High yttrium structure alloy containing 90% yttrium can be used in aviation and other occasions requiring low density and high melting point.

6. The yttrium-doped SrZrO3 high-temperature proton conducting material, which has attracted much attention at present, is of great significance to the production of fuel cells, electrolyzers and gas sensors that require high hydrogen solubility.

7. Yttrium is also used in high temperature resistant spray materials, diluents for nuclear reactor fuels, permanent magnet material additives and as getters in the electronics industry.
