Product details

Model Number: GK-729 Brand Name: GENPHOAL Key Specifications/Special Features: Gallium is achemical elementwith symbolGaandatomic number31Elemental gallium does not occur in free form in nature, but as the gallium (III) compounds that are in trace amounts inzincores and inbauxiteGallium is a soft silvery metal, and elemental gallium is a brittle solid at low temperaturesIf it is held in the human hand long enough, gallium will melt, since it melts at the temperature of about 29.76°C (85.57°F) (slightly aboveroom temperature)Melting point of gallium is used as a temperature reference pointAlloygalinstan(68.5% gallium, 21.5%indium, and 10%tin) has an even lower melting point of 19°C (2°F), well below the freezing point of waterBeginning with its discovery in 1875 through the era ofsemiconductors, gallium was used primarily as an agent to makealloysthat melt at low temperaturesGallium became useful in semiconductors, including as adopantToday, nearly all gallium is used inelectronicsGallium arsenide, the primarychemical compoundof gallium in electronics, is used inmicrowavecircuits, high-speed switching circuits, andinfraredcircuitsGallium nitrideand indium gallium nitride, minority semiconductor uses, produce blue and violetlight-emitting diodes(LEDs) anddiode lasersGallium has no known role in biology
Because gallium (III) andferricsalts behave similarly in biological systems, gallium ions often mimicironions in medical applications
Some pharmaceuticals containing gallium and radiopharmaceuticalshave been used rarely
Physical properties:
Galliumattacksmost other metals bydiffusinginto their metallattice
Gallium for example, diffuses into thegrain boundariesofaluminium-zincalloys [2]or steel, [3]making them very brittle
Gallium easily alloys with many metals, and is used in small quantities as aplutonium-gallium alloyin the plutoniumcoresof nuclear bombs, to help stabilize the plutonium crystal structure
[4] Elemental gallium is not found in nature, but it is easily obtained bysmelting
Very pure gallium metal has a brilliant silvery color and its solid metal fracture conchoidal likeglass
Gallium metal expands by 3.1% when it solidifies, and therefore storage in either glass or metal containers is avoided, due to the possibility of container rupture with freezing
Gallium shares the higher-density liquid state with only a few materials, likewater,silicon,germanium,bismuth, and plutonium
