Performance description: 20-30nm high
specific surface area nano yttrium oxide, specific surface area of 100m2/g is
widely used in catalyst carrier；30-50nm
nano yttrium oxide has very good fluidity, used as an additive and a package.
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.
