Editing Rhodium (section)

===Other uses===
Rhodium is used as an alloying agent for hardening and improving the corrosion resistance<ref name="ASM13B" /> of [[platinum]] and [[palladium]]. These alloys are used in furnace windings, bushings for glass fiber production, [[thermocouple]] elements, [[electrode]]s for aircraft [[spark plug]]s, and laboratory crucibles.<ref>{{Cite book|author= Lide, David R|title= CRC handbook of chemistry and physics 2004–2005: a ready-reference book of chemical and physical data|year=2004|publisher=CRC Press|location=Boca Raton|isbn=978-0-8493-0485-9 |edition=85th |pages=4–26|url=https://books.google.com/books?id=WDll8hA006AC}}</ref> Other uses include:

* Rhodium neutron detectors are used in nuclear reactors to measure neutron flux levels—this method requires a digital filter to determine the current neutron flux level, generating three separate signals: immediate, a few seconds delay, and a minute delay, each with its own signal level; all three are combined in the rhodium detector signal. The three [[Palo Verde Nuclear Generating Station|Palo Verde]] nuclear reactors each have 305 rhodium neutron detectors, 61 detectors on each of five vertical levels, providing an accurate 3D "picture" of reactivity and allowing fine tuning to consume the nuclear fuel most economically.<ref>{{cite journal

In automobile manufacturing, rhodium is also used in the construction of headlight reflectors.<ref name="Stwertka">Stwertka, Albert. ''A Guide to the Elements'', Oxford University Press, 1996, p. 125. {{ISBN|0-19-508083-1}}</ref>
