é’†(Gd)
In 1880, G. de Marignac of Switzerland separated the "é’" into two elements, one of which was confirmed by Sorit to be a strontium element, and the other element was confirmed by the study of Pois Baudler. In 1886, in order to commemorate the discoverers of the enamel elements, Marignac studied the rare earth pioneer Dutch chemist Gado Linium and named the new element é’†.
é’† will play an important role in modern technological innovation.
Its main uses are:
(1) Its water-soluble paramagnetic complex can medically improve the nuclear magnetic resonance (NMR) imaging signal of the human body.
(2) Its sulfur oxide can be used as a substrate grid of a special brightness oscilloscope and an x-ray screen.
(3) The ruthenium in yttrium gallium garnet is an ideal single substrate for the bubble memory.
(4) It can be used as a solid magnetic refrigerant medium without the Camot cycle limitation.
(5) Used as an inhibitor to control the chain reaction level of nuclear power plants to ensure the safety of nuclear reactions.
(6) It is used as an additive for samarium-cobalt magnets to ensure that the properties do not change with temperature.
Both strontium and its isotopes are the most effective neutron absorbers and can be used as inhibitors in nuclear reactors.
