Dysprosium is a chemical element; it has symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster. Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime.

Naturally occurring dysprosium (66 Dy) is composed of 7 stable isotopes, 156 Dy, 158 Dy, 160 Dy, 161 Dy, 162 Dy, 163 Dy and 164 Dy, with 164 Dy being the most abundant (28.18% natural abundance). Twenty-nine radioisotopes have been characterized ...
Didysprosium trisulfide forms yellow-orange-brown crystals of two modifications: cubic and monoclinic systems. [5] There is evidence that Dy2S3 forms crystals of brown-red, black, or green color. The crystals are stable in dry air, but in humid air they are slowly hydrolyzed. The compound is moderately soluble in water and acids.

Under standard conditions, the elements dysprosium and tin combine to form a number of intermetallic compounds, the dysprosium stannides. Dysprosium stannides with simple empirical formulas include Dy 5 Sn 3 and DySn 2, but four other intermetallics have intermediate composition. None is believed to survive temperatures higher than 1,866 °C ...
Dysprosium oxide (Dy 2 O 3) is a sesquioxide compound of the rare earth metal dysprosium. It is a pastel yellowish-greenish, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers, dysprosium metal halide lamps, and as a Faraday rotator. [3] It can react with acids to produce the corresponding dysprosium(III ...
