use:

1. High nano yttrium oxide high-temperature proton conductive material containing nano yttrium oxide up to 90%, which can be used in the production of fuel cells, electrolytic cells and gas sensors requiring high hydrogen solubility.

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

3. High specific surface area nano yttrium oxide, catalyst carrier.

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

5. High nano yttrium structure alloy containing nano yttrium oxide up to 90%, which can be applied to aerospace and other applications requiring low density and high melting point.

6. Additives for steel and non-ferrous alloys. FeCr alloy usually contains 0.5% to 4% nano yttrium oxide. Nano yttrium oxide can enhance the oxidation resistance and ductility of these stainless steels. After adding proper amount of nano yttrium oxide mixed rare earth in MB26 alloy, the comprehensive performance of the alloy is obviously improved. It can replace some medium-strength aluminum alloys on the force-bearing members of the aircraft; adding a small amount of nano yttrium lanthanum oxide rare earth in the Al-Zr alloy can improve the electrical conductivity of the alloy; the alloy has been adopted by most domestic wire factories; The addition of nano yttrium oxide improves electrical conductivity and mechanical strength.

In addition, nano yttrium oxide is also used in high temperature resistant spray materials, thinner for atomic reactor fuels, permanent magnet material additives, and as a getter in the electronics industry.
