SPI Supplies® SPI # 02754-AB 15 Rare Earth Element Standard Serial YQ
Details ofthe 15 different items in SPI Supplies® 02754-AB Rare Barths Standard Serial YQ are givenin the following pages. Metals and synthetic fluorides have been chosen for their stability. The purityand form of each grain and its source or manufacturer have been indicated. Full suppliers' lot specificdata are held on file at SPI Supplies for reference.
The photographs are of the actual grains in this particular mount. The X-ray spectra are taken fromgrains of the same batch, and are given as an assurance that the material is in fact what is claimed.These spectra were generated by a 15keV electron beam and collected with a Kevex energy-dispersivespectrometer with a resolution of 190eV, sensitive to X-rays greater than 0.6keV The use of a 20kVelectron beam would enhance the sensitivity of the heaviest rare earth elements. In all cases, spectra areconsistent with the compositions given.
