What are the uses of gallium?
It has important uses in Blu-ray technology, mobile phones, blue and green LEDs and pressure sensors for touch switches. Gallium readily alloys with most metals. It is particularly used in low-melting alloys. It has a high boiling point, which makes it ideal for recording temperatures that would vaporise a thermometer.
Who was gallium discovered by?
Paul-Émile Lecoq de BoisbaudranGallium / DiscovererPaul-Émile Lecoq de Boisbaudran, also called François Lecoq de Boisbaudran, was a French chemist known for his discoveries of the chemical elements gallium, samarium and dysprosium. Wikipedia
What was gallium used for in the past?
Gallium easily forms alloys with most metals and has been used to create low melting alloys. Gallium is used as a doping material for semiconductors and has been used to produce solid-state items like transistors and light emitting diodes.
What are the special properties of gallium?

How is gallium used in smartphones?
Gallium provides light emitting diode (LED) backlighting. Bauxite is the pri- mary source of this commodity. Sphalerite is the source of indium (used in the screen’s conductive coating) and germanium (used in displays and LEDs). The content of copper in a mobile device far exceeds the amount of any other metal.
How much is gallium cost?
Gallium is expected to trade at 2149.25 CNY/Kg by the end of this quarter, according to Trading Economics global macro models and analysts expectations.
Does gallium float in water?
Gallium is about 6-times the density of water. The density of aluminum is only 3-times the density of water, so a soda can would float on top of liquid gallium. Melting Point: 76 °C. Boiling Point: 2204 °C.
What is the rare metal in cell phones?
Capacitors made of the rare, hard, blue-gray metal tantalum are used for filtering and frequency tuning. Nickel is also used in capacitors and in mobile phone electrical connections.
Which metal is used in mobile phone battery?
Lithium
Lithium is primarily used in the production of mobile-phone batteries.
What is gallium worth?
Gallium is expected to trade at 2149.25 CNY/Kg by the end of this quarter, according to Trading Economics global macro models and analysts expectations. Looking forward, we estimate it to trade at 2273.90 in 12 months time.
Can I eat gallium?
Is gallium toxic? Gallium metal is considered safe to play with and handle, and is considered non-toxic in its elemental form. Gallium compounds are mildly toxic, they are not considered dangerous but should not be inhaled or ingested.
Why is gallium expensive?
Due to the rarity of the element, gallium is only used to a limited extent. Various gallium compounds are made from most of the gallium produced.
Is gallium expensive metal?
Not surprisingly then, consumption of gallium rose has grown with global appetite for these devices. Between 2000 and 2008, the average gallium metal price (99.99% min.) ranged between US$ 200 and US$ 400 per kilogram.
Does iPhone have gold in it?
Apple and other smartphone manufacturers use gold for pins, relays, and connectors — components that send signals or need to remain flexible for the lifetime of the device. In iPhones — by far the most popular smartphone brand in the United States — cameras, wireless charging coils, and logic boards all use gold.
What metal is used in Tesla batteries?
Tesla is changing the battery cell chemistry that it uses in its standard range vehicles, the automaker said Wednesday in its third-quarter investor deck. The new batteries will use a lithium-iron-phosphate (LFP) chemistry rather than nickel-cobalt-aluminum which Tesla will continue to use in its longer-range vehicles.
