Yttrium Oxide is white in color with a melting point of 2,410°C, a density of 5.01 g/cc, and a vapor pressure of 10-4 Torr at ~2,000°C. It is considered to be the most important yttrium compound. Yttrium oxide is used to make phosphors which provide the color red in televisions and yttrium iron garnets are an important element of microwave filters.
SAM specializes in producing up to 99.999% high purity evaporation materials using quality assurance processes to guarantee product reliability. The materials are used in deposition processes including semiconductor deposition, chemical vapor deposition (CVD) and physical vapor deposition (PVD)and mainly for optics including wear protection, decorative coatings, and displays.
Various shapes, such as tablets, granules, rods and wires are available. Customized forms and quantity are also available upon request. SAM also provides evaporation sources, boats, filaments, crucibles and heaters, and e-beam crucible liners.
