Dysprosium monosulfide is a binary inorganic compound of dysprosium and sulfur with the chemical formula DyS. [1] [2] [3]
Heating stoichiometric amounts of pure substances in an inert atmosphere:
Dysprosium monosulfide forms crystals of cubic system, space group Fm3m, cell parameters a = 0.5591 nm, Z = 4, isomorphous with NaCl.
The compound melts congruently at a temperature of 2360 °C. [4]
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 is composed of seven isotopes, the most abundant of which is 164Dy.
Sulfur (also spelled sulphur in British English) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
Ammonium hydrosulfide is the chemical compound with the formula [NH4]SH.
Sulfur compounds are chemical compounds formed the element sulfur (S). Common oxidation states of sulfur range from −2 to +6. Sulfur forms stable compounds with all elements except the noble gases.
Copper monosulfide is a chemical compound of copper and sulfur. It was initially thought to occur in nature as the dark indigo blue mineral covellite. However, it was later shown to be rather a cuprous compound, formula Cu+3S(S2). CuS is a moderate conductor of electricity. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H2S, is bubbled through solutions of Cu(II) salts. It is one of a number of binary compounds of copper and sulfur (see copper sulfide for an overview of this subject), and has attracted interest because of its potential uses in catalysis and photovoltaics.
Titanium(II) sulfide (TiS) is an inorganic chemical compound of titanium and sulfur.
Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores.
Copper(I) sulfide is a copper sulfide, a chemical compound of copper and sulfur. It has the chemical compound Cu2S. It is found in nature as the mineral chalcocite. It has a narrow range of stoichiometry ranging from Cu1.997S to Cu2.000S. Samples are typically black.
Samarium monosulfide is a binary inorganic chemical compound of samarium metal and sulfur with the chemical formula SmS.
Dysprosium(II) chloride (DyCl2), also known as dysprosium dichloride, is an ionic chemical compound of dysprosium and chlorine. This salt is a reduced compound, as the normal oxidation state of dysprosium in dysprosium compounds is +3.
Dysprosium phosphide is an inorganic compound of dysprosium and phosphorus with the chemical formula DyP.
Neodymium(III) sulfide is a inorganic chemical compound with the formula Nd2S3 composed of a two neodymium atoms in the +3 oxidation state and three sulfur atoms in the -2 oxidation state. Like other rare earth sulfides, neodymium(III) sulfide is used as a high-performance inorganic pigment.
