Selected Ultra High Purity Semiconductor and Laser Crystals and Sputtering Targets

American Elements is the world's leading manufacturer of 99%, 99.9%, 99.99%, 99.999% and 99.9999% high purity metals and powders. American Elements specializes in the preparation and purification of compounds to ultra high purity standards: 2N, 3N, 4N, 5N and 6N with parts per million (ppm) and parts per billion (ppb) level impurities certified.

99.999% Uranyl Acetate Fine Powder

Managed by Ph.D.-level chemists with decades of high purity production experience, American Elements can purify materials that are known to be difficult to refine but are essential to many high tech applications and research. These include most metals, oxides, and fluorides, the entire rare earth (lanthanide) series, cobalt, europium, rhenium, rubidium, scandium, and others to 99.999% purity. We can reach high purity in forms such as nanoparticles and nanopowders, organo-metallic compounds, sputtering targets, foil, rod, pellets and wire; we also produce specialized high purity materials for fuel cells and solar energy applications.

99.999% Ultra High Purity Dysprosium Metal (Dy)Rare earth materials are often sold with a 99.99% purity designation, when in fact they are of lower unknown purity because many testing capabilities of production facilities in China calculate the purity of a specific rare earth element as a ratio based on other rare earths in the compound; the relative quantities of all other elements are assumed. Such producers will represent this type of purity as "RE/TREO". American Elements represents its 99.999% purity designation with respect to all elements on the periodic table - a significant advantage to our customers who are involved in the fields of high technology electronics, optics, and pharmaceutical manufacturing.

For example, American Elements can prepare aluminum chloride, erbium chloride and ytterbium chloride hydrates with iron and other transition metals less than 100 ppb. Similar purity levels can be obtained with the other rare earth chlorides.

Crystallography Laboratory showing Nd:YAG crystal growth in processWe produce palladium metal, palladium nitrate, and tetraamminepalladium(II) nitrate of 99.999% purity with levels of the above analytes in the low ppb range.

We have routinely prepared large batches of barium nitrate in a purity of 99.9999% with the largest impurity being strontium at less than .5 ppm. We synthesize cis-dichlorodiammineplatinum (II) in a purity of 99.999% with no other detectable heavy metals.

Among its technical capabilities, our high purity production facility includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors, all supported by our extensive analytical laboratory including X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis.
