Boron SampleBoron 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 Boron 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). Boron 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. Boron 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 research below. We also produce Boron 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. Boron samples vary in size and thickness.

Boron(B) atomic and molecular weight, atomic number and elemental symbolBoron (atomic symbol: B, atomic number: 5) is a Block P, Group 13, Period 2 element with an atomic weight of 10.81. Boron Bohr Model The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s2 2p1. The boron atom has a radius of 90 pm and a Van der Waals radius of 192 pm. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808. It was first isolated by Humphry Davy, also in 1808. Boron is classified as a metalloid is not found naturally on earth. Elemental Boron Along with carbon and nitrogen, boron is one of the few elements in the periodic table known to form stable compounds featuring triple bonds.Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. Boron is found in borates, borax, boric acid, colemanite, kernite, and ulexite.The name Boron originates from a combination of carbon and the Arabic word buraqu meaning borax.
