WebApr 10, 2024 · Here we report targeted high-pressure synthesis of two novel high- TC hydride superconductors, P 63 /mmc- ThH9 and Fm3m-ThH10, with the experimental critical temperatures ( TC) of 146 K and 159–161 K and upper critical magnetic fields 38 and 45 Tesla at pressures 170–175 Gigapascals, respectively. Superconductivity was evidenced … Web1. Introduction. Thorium and its hydrides are promising materials for advanced nuclear reactors with a high level of safety [1 – 8] and have attracted much attention. This is mainly due to their strength and stability at elevated temperatures while maintaining the desirable properties for neutron moderation. [] In general, thorium hydrides crystalize in ThH 2 and …

Superconductivity at 161 K in thorium hydride ThH10: Synthesis and …

Thorium reacts with hydrogen to form the thorium hydrides ThH2 and Th4H15, the latter of which is superconducting below the transition temperature of 7.5–8 K; at standard temperature and pressure, it conducts electricity like a metal. Thorium is the only metallic element that readily forms a hydride higher than … See more Many compounds of thorium are known: this is because thorium and uranium are the most stable and accessible actinides and are the only actinides that can be studied safely and legally in bulk in a normal laboratory. … See more All four thorium tetrahalides are known, as are some low-valent bromides and iodides: the tetrahalides are all hygroscopic compounds that … See more Many other inorganic thorium compounds with polyatomic anions are known, such as the perchlorates, sulfates, sulfites, nitrates, carbonates, … See more A thorium atom has 90 electrons, of which four are valence electrons. Four atomic orbitals are theoretically available for the valence electrons to occupy: 5f, 6d, 7s, and 7p. However, the 7p orbital is greatly destabilised and hence it is not occupied in the ground state … See more In air, thorium burns to form the binary oxide thorium dioxide, ThO2, also called thoria or thorina. Thoria, a refractory material, has the … See more The heavier chalcogens sulfur, selenium, and tellurium are known to form thorium chalcogenides, many of which have more complex structure … See more Most of the work on organothorium compounds has focused on the cyclopentadienyls and cyclooctatetraenyls. Like many of the early and middle actinides (thorium through americium, and also expected for curium), thorium forms the yellow … See more WebFeb 15, 2007 · Thorium hydrides are also attractive due to their potential use for advanced nuclear fuels because they can give higher total power and have a higher heavy metal … c: windows installer 能删吗
