Gadolinium - Wikipedia
WebThe lanthanum-gadolinium compounds were superconducting up to 1 at.% gadolinium and became ferromagnetic for the concentrations of gadolinium above 2.5 at. Recently some temary compounds of the formula MRh 4 B 4 , with B = as thorium, yttrium, neodymium, samarium, gadolinium, terbium, dysprosium, holmium, erbium, or lutetium, … WebIt is ferromagnetic (elements forms permanent magnet) at a temperature below 20 O C and paramagnetic (weakly attracted by external applied magnetic field) above this temperature. Gadolinium chemical symbol is Gd and atomic number is 64. Its atomic weight is 157.25. Gadolinium melting point is 1312 O C and boiling point is 3000 O C. Gadolinium is paramagnetic at room temperature, with a ferromagnetic Curie point of 20 °C (68 °F). Paramagnetic ions, such as gadolinium, increase nuclear spin relaxation rates, making gadolinium useful as a contrast agent for magnetic resonance imaging (MRI). See more Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element. … See more Gadolinium is named after the mineral gadolinite, in turn named after Finnish chemist and geologist Johan Gadolin. In 1880, the Swiss chemist Jean Charles Galissard de Marignac observed … See more Gadolinium is produced both from monazite and bastnäsite. 1. Crushed minerals are extracted with hydrochloric acid or sulfuric acid, which converts the insoluble oxides into soluble chlorides or sulfates. 2. The acidic filtrates are partially … See more As a free ion, gadolinium is reported often to be highly toxic, but MRI contrast agents are chelated compounds and are considered safe enough to be used in most persons. The toxicity of free gadolinium ions in animals is due to interference with a … See more Physical properties Gadolinium is the eighth member of the lanthanide series. In the periodic table, it appears between the elements europium to its left and terbium to its right, and above the actinide curium. It is a silvery-white, malleable See more Gadolinium is a constituent in many minerals such as monazite and bastnäsite. The metal is too reactive to exist naturally. Paradoxically, as noted above, the mineral gadolinite actually contains only traces of this element. The abundance in the Earth's crust is about 6.2 … See more Gadolinium has no large-scale applications, but it has a variety of specialized uses.
