American Elements is capable of producing materials to many standard grades including:
Mil Spec (military grade),
US Pharmacopeia (USP) grade,
and European Pharmacopoeia/British Pharmacopoeia (EP/BP) grade.
In addition, American Elements can purify many materials to high percentages of absolute purity—up to 99.9999% in some cases—at our high purity production facility. Among its technical capabilities, this facility includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, and 50 gallon glass-lined Pfaudler reactors. Production of high purity materials is overseen by Ph.D. chemists and supported by our extensive analytical laboratory, which uses atomic spectroscopy, x-ray diffraction analysis, scanning electron microscopy, and BET surface area analysis, among other technologies, to ensure that the elemental composition and structural properties of each product rigorously adhere to our standards.
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, fluorides, the entire rare earth (lanthanide) series, cobalt, europium, rhenium, rubidium, scandium, and others to 99.999% purity. We can reach high purities in forms such as organometallic compounds, sputtering targets, foils, rods, pellets and wires; we also produce specialized high purity materials for fuel cells and solar energy applications.
American Elements can prepare aluminum chloride, erbium chloride and ytterbium chloride hydrates with iron and other transition metal impurities less than 100 ppb. Similar purity levels can be obtained with the other rare earth chlorides.
We 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.
Crystal Synthesis and Substrates
American Elements' crystal growth production emphasizes ultra high purity elemental and compound materials produced in the form of single crystals, polycrystalline pieces, boules, and crackle, powders, ingots, discs, shaped charges and rods. We are recognized specialists in custom-grown single and polycrystalline materials of any of the III-V and II-VI compounds when special orientations, purities or dopants are required. Unlike many other producers, our facilities are also set up to cost-effectively produce small or pilot scale lots. All production materials are analyzed and certified prior to shipping.
American Elements produces custom combinations of layers and substrates for both commercial and research applications. For example, we can produce many custom variations of metallic nitride layers on various aluminum oxide-based substrates. We provide metallization for these materials and our other products.
American Element's crystal synthesis facility is equipped to synthesis crystalline structures using a variety of established technologies, including:
- Crystal "pulling" by the Czochralski method for production of semiconductor materials
- Flux growth and gradient freeze
- Directional solidification of fluorites using both the Bridgman-Stockbarger and float zoning techniques
Anhydrous/Ultra Dry Materials
American Elements specializes in the production of Ultra Dry and Anhydrous formulations for oxygen and moisture-sensitive applications. Ultra dry materials are produced to high purity (up to 99.9999%) and packaged in an argon atmosphere to minimize introduction of impurities.
