High purity selenium pieces, powder, and other forms can serve as precursor materials for the MBE growth of semiconductor crystals such as cadmium selenide (CdSe), lead selenide (PbSe), zinc selenide (ZnSe), copper indium gallium selenide (CIGS), and other selenides. These materials are used primarily in thin film solar cells and LEDs/OLEDs, particularly as quantum dots (QDs). American Elements quantum dot products include CdSe, PbSe, CdSe/ZnS, and others. Ultra high purity selenium is also used as an ingredient in some health supplements and beauty products. We also manufacture selenium in other purities and forms (see selenium metal).

Selenium is a solid with a single gray metallic luster, brittle, toxic, conductive, and its conductivity changes sharply with the intensity of light. Selenium is an essential trace mineral nutrient for human body, but excessive intake can be harmful to human body. The amount of selenium in the earth's crust is only 0.05 ppm, and its distribution is scattered and the annual supply is limited.

The metal indium is burned in the air or obtained by heating hydroxide, nitrate or carbonate. Used in glass manufacturing.</p><p><strong>Available forms:</strong></p><p>4N In2O3 powder</p><p><strong>Certificate of Analysis:</strong></p><div><table><tbody><tr><td><p><strong>Detecting Element(%, less than)</strong></p></td></tr><tr><td><p>Grade</p></td><td><p>In2O3</p></td><td><p>In</p></td><td><p>Cl</p></td><td><p>Cauterant Decrease</p></td><td><p>Al</p></td><td><p>As</p></td><td><p>Cd</p></td><td><p>Cu</p></td><td><p>Fe</p></td><td><p>Pb</p></td></tr><tr><td><p>4N In2O3</p></td><td><p>≥99.99</p></td><td><p>≥81.5</p></td><td><p>≤0.5</p></td><td><p>≤0.5</p></td><td><p>0.0010</p></td><td><p>0.0005</p></td><td><p>0.0010</p></td><td><p>0.0008</p></td><td><p>0.0010</p></td><td><p>0.0015</p></td></tr><tr><td></td><td></td><td><p>Sb</p></td><td><p>Sn</p></td><td><p>Tl</p></td><td><p>Zn</p></td><td></td><td></td><td></td><td></td><td><p>Total</p></td></tr><tr><td></td><td></td><td><p>0.0005</p></td><td><p>0.0012</p></td><td><p>0.0010</p></td><td><p>0.0015</p></td><td></td><td></td><td></td><td></td><td><p>0.01</p></td></tr></tbody></table></div>"
