1. Additives for steel and non-ferrous alloys. FeCr alloys usually contain 0.5% to 4% nano-yttrium oxide. Nano-yttrium oxide can enhance the oxidation resistance and ductility of these stainless steels. After adding an appropriate amount of nano-rich yttrium oxide mixed rare earth to MB26 alloy, the overall performance of the alloy is significantly improved , Can replace part of the medium-strength aluminum alloy used in the stressed components of the aircraft.

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

3. Use 400 watts of nano neodymium aluminum garnet laser beam to drill, cut and weld large components.

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

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

6. The high nanometer yttrium oxide high-temperature proton conductive material containing 90% nanometer yttrium oxide can be used in the production of fuel cells, electrolytic cells and gas sensors that require high hydrogen solubility.

In addition, nano-yttrium oxide is also used in high-temperature spray materials, diluents for nuclear reactor fuels, additives for permanent magnetic materials, and as getters in the electronics industry.
