American Elements produces a wide range of glass and crystalline materials for optical, laser, lighting, electronics and other applications. Optical products are engineered to meet the most rigorous quality standards and produced from ultra-high purity materials. Production of crystalline materials is overseen by experts at our state-of-the-art crystal synthesis facilities utilizing Bridgman-Stockbarger, Czochralski and other established methods. Our glass production products include (1) glass batch, (2) glass colorants, (3) lighting glass and (4) glass polishes. BatchBrite™ is a proprietary formulation used to whiten typical glass batch compositions; particularly when high iron content is of concern. Cerafine™ is a proprietary formulation of cerium-based glass polish for very fine polish steps and glass beveling.

Innovation Case Study #7: American Elements Synthesizes New Optical Crystal Structure for U.S. Military

#7: American Elements Synthesizes New Optical Crystal Structure for U.S. Military


The Challenge: 
In 2002, American Elements was approached by Oak Ridge National Laboratory (ORNL) to assist with its basic research into innovative methods to measure temperatures inside jet engines. ORNL had explored the usefulness of several classes of laser crystals and hypothesized that doping yttrium-aluminum garnet (YAG) with dysprosium could yield desired results. While YAG doped with neodymium (Nd:YAG) is today ubiquitous in medical surgical laser, Dy:YAG had never been synthesized.

The Innovation: 
American Elements accepted the challenge of growing a Dy:YAG crystal. After analyzing existing literature on the subject which suggested that pressures and temperatures much higher than that required to grow a Nd:YAG crystal would be required, American Elements built a custom Bridgman-Stockbarger float zoning pilot scale line to grow the Dy:YAG material.

The Result: 
The Bridgman-Stockbarger facility generated 3 x 2-3 mm high purity Dy:YAG crystals which were delivered to Oakridge for testing. The results of the tests are proprietary to ORNL and the U.S. Air Force.
