Gallium SampleGallium samples are suitable for metallurgical analysis, chemical analysis, physical testing, mechanical testing, failure analysis, fire & flammability testing, contaminant identification and weatherization studies. Metallurgical testing is used to determine quality by analyzing the microstructure of a sample under a microscope. American Elements specializes in producing irregular shaped Gallium Samples with the highest possible density and smallest possible average grain sizes for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Gallium samples are available in dimensions appropriate for numerous testing procedures. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. Gallium samples are suitable for metallurgical analysis, chemical analysis, physical testing, mechanical testing, failure analysis, fire & flammability testing, contaminant identification and weatherization studies. Metallurgical testing is used to determine quality by analyzing the microstructure of a sample under a microscope. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. See safety data and research below and pricing/lead time above. We also produce Gallium as rod, ingot, powder, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request. A wide variety of American Elements products are available in sample form for materials and metallurgical testing procedures. Gallium samples vary in size and thickness.

Gallium (Ga) atomic and molecular weight, atomic number and elemental symbolGallium (atomic symbol: Ga, atomic number: 31) is a Block P, Group 13, Period 4 element with an atomic weight of 69.723. Gallium Bohr ModelThe number of electrons in each of Gallium's shells is 2, 8, 18, 3 and its electron configuration is [Ar] 3d10 4s2 4p1. The gallium atom has a radius of 122.1 pm and a Van der Waals radius of 187 pm. Gallium was predicted by Dmitri Mendeleev in 1871. It was first discovered and isoalted by Hans Christian Oersted in 1825. Elemental Gallium In its elemental form, gallium has a silvery appearance. Gallium is one of three elements that occur naturally as a liquid at room temperature, the other two being mercury and cesium. Gallium does not exist as a free element in nature and is sourced commercially from bauxite and sphalerite. Currently, gallium is used in semiconductor materials for microelectronics and optics. The element name originates from the Latin word 'Gallia', the old name of France, and the word 'Gallus,' meaning rooster.
