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.

ErSee more Erbium products. Erbium (atomic symbol: Er, atomic number: 68) is a Block F, Group 3, Period 6 element with an atomic radius of 167.259. 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. Elemental Erbium PictureErbium is a member of the lanthanide or rare earth series of elements. 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.

Free Test Sample Program

We recognize many of our customers are purchasing small quantities directly online as trial samples in anticipation of placing a larger future order or multiple orders as a raw material for production. Since our primary business is the production of industrial quantities and/or highly consistent batches which can be used for commercial production and purchased repeatedly in smaller quantity, American Elements offers trial samples at no charge on the following basis. Within 6 months of purchasing materials directly online from us, you have the option to refer back to that order and advise that it is the intention of your company, institution or lab to either purchase a larger quantity, purchase the material in regular intervals or purchase more on some other basis.

We will then evaluate your future needs and assuming the quantity or number of future purchases qualify, we will fully credit your purchase price with the next order. Because of the many variables in the quantity and number of orders you may place, it is impossible to evaluate whether your future order(s) will qualify for this program prior to your placing your next order. Please know American Elements strongly desires to make this free sample program available to you and will make every effort to do so once your next order is placed.
