Paul Emile Lecoq de Boisbaudran discovered gallium in 1875 using a spectroscope. |
He later isolated the metal by electrolysis. |
Some of the alloys of gallium with other metals are liquid at room temperature. |
This property made gallium an early metal for thermometric uses. |
Now, gallium is primarily important for microelectronics, specifically microwaves. |
Gallium is also used to produce blue or violet LEDs. |
Gallium does not occur in its natural elemental state, but is extracted from several minerals. |
Once it is extracted, its purest form has an intense silver color. |
When gallium is added to many metals, such as steel, it causes them to become brittle. |
Gallium actually alloys quite readily to other metals. |
One of gallium's most interesting properties is its ability to be a liquid when held in a human hand. |
It then refreezes when removed from the hand. |
Gallium often supercool below its melting and freezing points. |
Because of its state at normal temperatures, gallium is used as a reference point in the International Temperature Scale of 1990. |
Of all the metals, gallium has one of the largest ranges in which it is a liquid. |
Gallium does not react with air or water because of its oxide layer. |
Gallium is present on Earth at around 16.9 parts per million. |
Today, the main role of gallium in industry is in building semiconductors. |
Semiconductors account for about 98% of the gallium use in the US alone. |
Gallium does not seem to play a role in plant or animal biology. |
Gallium salts are used in the pharmaceutical and radiopharmaceutical industries. |
Gallium ions appear to have antibiotic properties, causing bacteria to die. |
Researchers are currently studying the oral intake of gallium for the treatment of several cancers. |
