Gallium and its derivatives have only found applications in recent decades. [[Gallium arsenide]] has been used in [[semiconductors]], in [[amplifiers]], in solar cells (for example in [[satellites]]) and in tunnel [[diode]]s for FM transmitter circuits. Gallium alloys are used mostly for dental purposes. Gallium ammonium chloride is used for the leads in [[transistors]].<ref>{{Cite book|title=Metallurgy for the non-metallurgist |last=Chandler |first=Harry |page=59 |publisher=ASM International |year=1998 |isbn=0-87170-652-0 |url=https://books.google.com/books?id=arupok8PTBEC&pg=PA59 }}</ref> A major application of gallium is in [[LED]] lighting. The pure element has been used as a [[dopant]] in semiconductors,{{citation needed|date=February 2013}} and has additional uses in electronic devices with other elements. Gallium has the property of being able to 'wet' glass and porcelain, and thus can be used to make mirrors and other highly reflective objects. Gallium can be added to alloys of other metals to lower their melting points.
