High-tech applications are often only viable if raw materials with specific high purity levels are available. Ultrathin metal or oxide layers needed in the electronics and semiconductor industry are made via evaporation or sputtering methods. High purity raw materials are the common basis for these processes and enable the formation of defect-free thin films with the required electrical or optical properties. Here at Keeling & Walker, we provide high purity tin oxides with a minimum purity of 99.99%. We can also provide tin oxide with specific limits for individual trace elements. We offer high purity materials based on thermal oxidation, as well as from wet chemical processes. Thermox RL-HP offers a small particle size and a uniform and narrow particle size distribution, with excellent sintering properties to allow highly dense and stable target materials to be manufactured. For radiochemical applications, high purity alphastannic acid (HPASA), as a largely amorphous tin oxide, offers high ion-exchange capacity for specific radionuclides, a well-defined particle size distribution and is manufactured in an environment suitable for pharmaceutical use. Applications of High Purity grades include: * Laser Glass manufacturing * Glass Refining Additive for low expansion Glass * Sputtering Target materials * Advanced Battery materials * Medical and Cosmetic applications Key Products:
