Boride IonErbium Boride is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Borides are hard, high-melting materials with metal-like conductivity. They are stable to nonoxidizing acids but break down in strong oxidizing agents and strong alkalis. Borides are used in semiconductors, superconductors, diamagnetic, paramagnetic, ferromagnetic, anti-ferromagnetic, turbine blades, and rocket nozzles. Borides have recently been discovered to be superconductive and ultra-incompressible. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Erbium Bohr Modelhe number of electrons in each of Erbium's shells is [2, 8, 18, 30, 8, 2] and its electron configuration is [Xe]4f12 6s2. The erbium atom has a radius of 176 pm and a Van der Waals radius of 235 pm. Erbium was discovered by Carl Mosander in 1843. Sources of Erbium include the mineral monazite and sand ores. Erbium is a member of the lanthanide or rare earth series of elements.Elemental Erbium Picture In its elemental form, erbium is soft and malleable it is fairly stable in air and does not oxidize as rapidly as some of the other rare earth metals. Erbiums ions fluoresce in a bright pink color, making them highly useful for imaging and optical applications. It is named after the Swedish town, Ytterby where it was first discovered.
