Home Products Thin Film Deposition Materials PVD Thin Film Deposition Materials List Thorium and Thorium Fluoride Alternatives WE OFFER CHOICES-THORIUM COMPOUNDS & NON-RADIOACTIVE THORIUM FLUORIDE ALTERNATIVES Thorium compounds are radioactive, flammable, heat-resistant elements with high melting points. For those reasons, manufacturing them requires considerable knowledge and experience in order to meet customers’ precise needs as well as comply with government hazardous materials regulations. As an option for one of those radioactive compounds - thorium fluoride - Materion manufactures a number of specialty compositions as alternatives. Depending on your application, you may want to consider the advantages of such a replacement. TECHNICAL APPLICATIONS USING THORIUM COMPOUNDS Thorium, and particularly thorium fluoride, has a number of industrial or commercial uses where their high melting point and ability to enhance strength are advantages. Among these applications are: Anti-reflective coatings Catalysts Optical coatings Heat resistant crucibles Vacuum tubes – such as magnetron tubes found in microwave ovens Ceramics AVAILABLE MATERION THORIUM COMPOUNDS & FORMS Custom thin film PVD thorium compounds are available in a wide variety of sputtering target geometries and evaporation forms including pieces, granules, powders, pellets, slugs, and wire. Radioactive compositions available: Thorium Fluoride ThF4 Thorium Nitrate Th(NO3)4-4H2O Thorium Oxide ThO2 Search our Inorganic Chemicals Online Catalog for thorium compounds and other chemical compositions. WHY THE SWITCH TO NON-RADIOACTIVE THORIUM FLUORIDE? The potential threat presented by radioactivity to health and environment is the reason thorium has been phased out of use for applications that do not explicitly require its presence. There are still no suitable alternatives for all thorium compounds, but the shift to safer replacements offers choices to concerned customers. AVAILABLE ALTERNATIVE FLUORIDE COMPOUNDS Materion manufactures the following specialty evaporation fluorides as replacements for those requiring non-radioactive thorium fluoride compositions for their application. All materials are typically available in 99.9% purity except for aluminum fluoride at 99.5%.
