Editing Zirconium (section)

=== Space and aeronautic industries ===

Materials fabricated from zirconium metal and ZrO<sub>2</sub> are used in space vehicles where resistance to heat is needed.<ref name="Stwertka">{{cite book|last=Stwertka|first=Albert|title=A Guide to the Elements|publisher=Oxford University Press|date=1996|pages=117–119 |isbn= 978-0-19-508083-4}}</ref>

High temperature parts such as combustors, blades, and vanes in [[jet engine]]s and stationary [[gas turbine]]s are increasingly being protected by thin [[ceramic]] layers and/or paintable coatings, usually composed of a mixture of zirconia and [[yttria]].<ref>{{multiref2|{{cite journal|doi= 10.1115/1.2906801|title= The Evolution of Thermal Barrier Coatings in Gas Turbine Engine Applications|date= 1994|last1= Meier|first1= S.

Zirconium is also used as a material of first choice for [[hydrogen peroxide]] ({{chem2|H2O2}}) tanks, propellant lines, valves, and thrusters, in [[Spacecraft propulsion|propulsion space systems]] such as these equipping the [[Sierra Space]]'s [[Dream Chaser]] [[spaceplane]]<ref name="Clark2023" /> where the [[thrust]] is provided by the [[combustion]] of [[kerosene]] and hydrogen peroxide, a powerful, but unstable, [[oxidizer]]. The reason is that zirconium has an excellent [[Corrosion#Resistance to corrosion|corrosion resistance]] to {{chem2|H2O2}} and, above all, do not [[catalysis|catalyse]] its spontaneous self-decomposition as the [[ion]]s of many [[transition metal]]s do.<ref name="Clark2023">{{cite web | last=Clark | first=Stephen | title=After decades of dreams, a commercial spaceplane is almost ready to fly | website=Ars Technica | date=2023-11-01 | url=https://arstechnica.com/space/2023/11/after-decades-of-dreams-a-commercial-spaceplane-is-almost-ready-to-fly/ | access-date=2023-11-03}}</ref><ref name="Zircadyne">{{cite web | author= ATI Materials | title=Zircadyne® 702/705 in Hydrogen Peroxide | url=https://www.atimaterials.com/Products/Documents/datasheets/zirconium/alloy/zircadyne_702_705_in_hydrogen_peroxide_v1.pdf | work= atimaterials | access-date=2023-11-03}}</ref>
